Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536636, here are decompositions:

7 + 31536629 = 31536636
23 + 31536613 = 31536636
29 + 31536607 = 31536636
97 + 31536539 = 31536636
107 + 31536529 = 31536636
137 + 31536499 = 31536636
233 + 31536403 = 31536636
239 + 31536397 = 31536636

Showing the first eight; more decompositions exist.
