Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497602, here are decompositions:
- 43 + 31497559 = 31497602
- 61 + 31497541 = 31497602
- 79 + 31497523 = 31497602
- 139 + 31497463 = 31497602
- 193 + 31497409 = 31497602
- 211 + 31497391 = 31497602
- 373 + 31497229 = 31497602
- 379 + 31497223 = 31497602
Showing the first eight; more decompositions exist.
