Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536536, here are decompositions:

7 + 31536529 = 31536536
37 + 31536499 = 31536536
139 + 31536397 = 31536536
223 + 31536313 = 31536536
313 + 31536223 = 31536536
349 + 31536187 = 31536536
439 + 31536097 = 31536536
487 + 31536049 = 31536536

Showing the first eight; more decompositions exist.
