Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535712, here are decompositions:
- 31 + 31535681 = 31535712
- 41 + 31535671 = 31535712
- 73 + 31535639 = 31535712
- 79 + 31535633 = 31535712
- 163 + 31535549 = 31535712
- 283 + 31535429 = 31535712
- 293 + 31535419 = 31535712
- 331 + 31535381 = 31535712
Showing the first eight; more decompositions exist.
