Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556386, here are decompositions:
- 5 + 31556381 = 31556386
- 83 + 31556303 = 31556386
- 107 + 31556279 = 31556386
- 137 + 31556249 = 31556386
- 353 + 31556033 = 31556386
- 419 + 31555967 = 31556386
- 479 + 31555907 = 31556386
- 509 + 31555877 = 31556386
Showing the first eight; more decompositions exist.
