Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556984, here are decompositions:

61 + 31556923 = 31556984
73 + 31556911 = 31556984
127 + 31556857 = 31556984
157 + 31556827 = 31556984
181 + 31556803 = 31556984
331 + 31556653 = 31556984
337 + 31556647 = 31556984
523 + 31556461 = 31556984

Showing the first eight; more decompositions exist.
