Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556288, here are decompositions:

139 + 31556149 = 31556288
277 + 31556011 = 31556288
307 + 31555981 = 31556288
331 + 31555957 = 31556288
349 + 31555939 = 31556288
367 + 31555921 = 31556288
397 + 31555891 = 31556288
571 + 31555717 = 31556288

Showing the first eight; more decompositions exist.
