Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577602, here are decompositions:
- 11 + 31577591 = 31577602
- 71 + 31577531 = 31577602
- 131 + 31577471 = 31577602
- 233 + 31577369 = 31577602
- 239 + 31577363 = 31577602
- 311 + 31577291 = 31577602
- 443 + 31577159 = 31577602
- 521 + 31577081 = 31577602
Showing the first eight; more decompositions exist.
