Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536884, here are decompositions:

13 + 31536871 = 31536884
37 + 31536847 = 31536884
61 + 31536823 = 31536884
151 + 31536733 = 31536884
271 + 31536613 = 31536884
277 + 31536607 = 31536884
487 + 31536397 = 31536884
523 + 31536361 = 31536884

Showing the first eight; more decompositions exist.
