Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536656, here are decompositions:

43 + 31536613 = 31536656
127 + 31536529 = 31536656
157 + 31536499 = 31536656
433 + 31536223 = 31536656
607 + 31536049 = 31536656
673 + 31535983 = 31536656
709 + 31535947 = 31536656
829 + 31535827 = 31536656

Showing the first eight; more decompositions exist.
