Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536686, here are decompositions:

73 + 31536613 = 31536686
79 + 31536607 = 31536686
157 + 31536529 = 31536686
283 + 31536403 = 31536686
373 + 31536313 = 31536686
463 + 31536223 = 31536686
499 + 31536187 = 31536686
739 + 31535947 = 31536686

Showing the first eight; more decompositions exist.
