Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536908, here are decompositions:

37 + 31536871 = 31536908
61 + 31536847 = 31536908
79 + 31536829 = 31536908
211 + 31536697 = 31536908
379 + 31536529 = 31536908
409 + 31536499 = 31536908
547 + 31536361 = 31536908
811 + 31536097 = 31536908

Showing the first eight; more decompositions exist.
