Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536626, here are decompositions:

13 + 31536613 = 31536626
19 + 31536607 = 31536626
97 + 31536529 = 31536626
127 + 31536499 = 31536626
223 + 31536403 = 31536626
229 + 31536397 = 31536626
313 + 31536313 = 31536626
439 + 31536187 = 31536626

Showing the first eight; more decompositions exist.
