Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556214, here are decompositions:

13 + 31556201 = 31556214
71 + 31556143 = 31556214
73 + 31556141 = 31556214
101 + 31556113 = 31556214
181 + 31556033 = 31556214
223 + 31555991 = 31556214
233 + 31555981 = 31556214
257 + 31555957 = 31556214

Showing the first eight; more decompositions exist.
