Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556516, here are decompositions:
- 37 + 31556479 = 31556516
- 109 + 31556407 = 31556516
- 127 + 31556389 = 31556516
- 163 + 31556353 = 31556516
- 193 + 31556323 = 31556516
- 223 + 31556293 = 31556516
- 367 + 31556149 = 31556516
- 373 + 31556143 = 31556516
Showing the first eight; more decompositions exist.
