Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536650, here are decompositions:

37 + 31536613 = 31536650
43 + 31536607 = 31536650
151 + 31536499 = 31536650
337 + 31536313 = 31536650
463 + 31536187 = 31536650
601 + 31536049 = 31536650
631 + 31536019 = 31536650
709 + 31535941 = 31536650

Showing the first eight; more decompositions exist.
