Checking p^11, only 2^11=2048 works since 3^11 is too large, giving one solution; now I'm working through the p^5·q case starting with p=2.\\n\\nFor p^5·q, p=2 gives 35 valid q values, p=3 gives 7, p=5 gives none, totaling 42.\\n\\nFor p^3·q^2, checking each base p=2,3,5,7,11 against the bound, I get 8+5+2+2+0=17 solutions total.\\n\\nNow I'm setting up the p^2·q·r case where p, q, r are distinct primes with q<r, working through the bound qr<1250 for p=2, then qr≤555 for p=3 excluding 3, and starting the p=5 case.\\n\\nContinuing with q=11: r<113.5, giving π(113)=30, minus 5 primes ≤11 leaves 25. Then q=13: r<96.08...\\n\\nq=13: r≤96, π(96)=24, exclude 6 → 18. q=17: r≤73, π=21, exclude 7 → 14. q=19: r≤65, π=18, exclude 8 → 10. q=23: r≤54, π=16, exclude 9 → 7. q=29: r≤43, π=14, exclude 10 → 4. q=31: r≤40, π=12, exclude 11 → 1. q=37: none left since r must exceed 37. Running total after adding these: 78+50+36+25+18+14+10+7+4+1 = 221, matching my tally so far.\\n\\nNow moving to p=3, requiring q<r, both distinct from 3, with qr≤555. I work through q=2 giving 57 valid r, q=5 giving 26, q=7 giving 18, q=11 giving 10, q=13 giving 7, q=17 giving 4, q=19 giving 2, and I'm now checking q=23 where r≤24 limits things further.\\n\\nContinuing q=3 gives 8, q=5 gives 4, q=11 none, so p=7 sums to 25.\\n\\nFor p=11: q=2 gives 6, q=3 gives 3, q=5 gives 1.\\n\\nMoving to p=13: q=2 gives 4, q=3 gives 2, q=5 gives none, totaling 6. Then p=17 sums to 4, p=19 gives 2, p=23 gives 1, so the p²qr total is 460.\\n\\nAdding everything up: 1+42+17+460 = 520. Let me double-check the p=2, q=3 case where 12r<5000 means r<416.67.\\n\\n\",\"signature\":\"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 truncated

Checking p^11, only 2^11=2048 works since 3^11 is too large, giving one solution; now I'm working through the p^5·q case starting with p=2.\\n\\nFor p^5·q, p=2 gives 35 valid q values, p=3 gives 7, p=5 gives none, totaling 42.\\n\\nFor p^3·q^2, checking each base p=2,3,5,7,11 against the bound, I get 8+5+2+2+0=17 solutions total.\\n\\nNow I'm setting up the p^2·q·r case where p, q, r are distinct primes with q<r, working through the bound qr<1250 for p=2, then qr≤555 for p=3 excluding 3, and starting the p=5 case.\\n\\nContinuing with q=11: r<113.5, giving π(113)=30, minus 5 primes ≤11 leaves 25. Then q=13: r<96.08...\\n\\nq=13: r≤96, π(96)=24, exclude 6 → 18. q=17: r≤73, π=21, exclude 7 → 14. q=19: r≤65, π=18, exclude 8 → 10. q=23: r≤54, π=16, exclude 9 → 7. q=29: r≤43, π=14, exclude 10 → 4. q=31: r≤40, π=12, exclude 11 → 1. q=37: none left since r must exceed 37. Running total after adding these: 78+50+36+25+18+14+10+7+4+1 = 221, matching my tally so far.\\n\\nNow moving to p=3, requiring q<r, both distinct from 3, with qr≤555. I work through q=2 giving 57 valid r, q=5 giving 26, q=7 giving 18, q=11 giving 10, q=13 giving 7, q=17 giving 4, q=19 giving 2, and I'm now checking q=23 where r≤24 limits things further.\\n\\nContinuing q=3 gives 8, q=5 gives 4, q=11 none, so p=7 sums to 25.\\n\\nFor p=11: q=2 gives 6, q=3 gives 3, q=5 gives 1.\\n\\nMoving to p=13: q=2 gives 4, q=3 gives 2, q=5 gives none, totaling 6. Then p=17 sums to 4, p=19 gives 2, p=23 gives 1, so the p²qr total is 460.\\n\\nAdding everything up: 1+42+17+460 = 520. Let me double-check the p=2, q=3 case where 12r<5000 means r<416.67.\\n\\n\",\"signature\":\"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 truncated
