Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556216, here are decompositions:
- 67 + 31556149 = 31556216
- 73 + 31556143 = 31556216
- 103 + 31556113 = 31556216
- 277 + 31555939 = 31556216
- 283 + 31555933 = 31556216
- 499 + 31555717 = 31556216
- 613 + 31555603 = 31556216
- 673 + 31555543 = 31556216
Showing the first eight; more decompositions exist.
