Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556312, here are decompositions:

3 + 31556309 = 31556312
19 + 31556293 = 31556312
163 + 31556149 = 31556312
199 + 31556113 = 31556312
313 + 31555999 = 31556312
331 + 31555981 = 31556312
373 + 31555939 = 31556312
379 + 31555933 = 31556312

Showing the first eight; more decompositions exist.
