Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556792, here are decompositions:
- 13 + 31556779 = 31556792
- 139 + 31556653 = 31556792
- 313 + 31556479 = 31556792
- 331 + 31556461 = 31556792
- 439 + 31556353 = 31556792
- 499 + 31556293 = 31556792
- 643 + 31556149 = 31556792
- 811 + 31555981 = 31556792
Showing the first eight; more decompositions exist.
