Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556152, here are decompositions:

3 + 31556149 = 31556152
11 + 31556141 = 31556152
53 + 31556099 = 31556152
71 + 31556081 = 31556152
281 + 31555871 = 31556152
311 + 31555841 = 31556152
389 + 31555763 = 31556152
491 + 31555661 = 31556152

Showing the first eight; more decompositions exist.
