Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556314, here are decompositions:

5 + 31556309 = 31556314
11 + 31556303 = 31556314
71 + 31556243 = 31556314
113 + 31556201 = 31556314
173 + 31556141 = 31556314
233 + 31556081 = 31556314
281 + 31556033 = 31556314
347 + 31555967 = 31556314

Showing the first eight; more decompositions exist.
