Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556304, here are decompositions:
- 11 + 31556293 = 31556304
- 61 + 31556243 = 31556304
- 103 + 31556201 = 31556304
- 163 + 31556141 = 31556304
- 191 + 31556113 = 31556304
- 223 + 31556081 = 31556304
- 271 + 31556033 = 31556304
- 293 + 31556011 = 31556304
Showing the first eight; more decompositions exist.
