Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612688, here are decompositions:
- 61 + 31612627 = 31612688
- 67 + 31612621 = 31612688
- 157 + 31612531 = 31612688
- 307 + 31612381 = 31612688
- 337 + 31612351 = 31612688
- 379 + 31612309 = 31612688
- 487 + 31612201 = 31612688
- 607 + 31612081 = 31612688
Showing the first eight; more decompositions exist.
