Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556016, here are decompositions:
- 5 + 31556011 = 31556016
- 17 + 31555999 = 31556016
- 47 + 31555969 = 31556016
- 59 + 31555957 = 31556016
- 67 + 31555949 = 31556016
- 83 + 31555933 = 31556016
- 109 + 31555907 = 31556016
- 139 + 31555877 = 31556016
Showing the first eight; more decompositions exist.
