Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529636, here are decompositions:

7 + 31529629 = 31529636
13 + 31529623 = 31529636
43 + 31529593 = 31529636
79 + 31529557 = 31529636
97 + 31529539 = 31529636
157 + 31529479 = 31529636
223 + 31529413 = 31529636
277 + 31529359 = 31529636

Showing the first eight; more decompositions exist.
