Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556362, here are decompositions:

53 + 31556309 = 31556362
59 + 31556303 = 31556362
83 + 31556279 = 31556362
113 + 31556249 = 31556362
263 + 31556099 = 31556362
281 + 31556081 = 31556362
491 + 31555871 = 31556362
521 + 31555841 = 31556362

Showing the first eight; more decompositions exist.
