Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536906, here are decompositions:

43 + 31536863 = 31536906
59 + 31536847 = 31536906
83 + 31536823 = 31536906
113 + 31536793 = 31536906
173 + 31536733 = 31536906
199 + 31536707 = 31536906
277 + 31536629 = 31536906
293 + 31536613 = 31536906

Showing the first eight; more decompositions exist.
