Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556364, here are decompositions:

11 + 31556353 = 31556364
23 + 31556341 = 31556364
41 + 31556323 = 31556364
61 + 31556303 = 31556364
71 + 31556293 = 31556364
163 + 31556201 = 31556364
223 + 31556141 = 31556364
251 + 31556113 = 31556364

Showing the first eight; more decompositions exist.
