Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476908, here are decompositions:

37 + 31476871 = 31476908
61 + 31476847 = 31476908
79 + 31476829 = 31476908
109 + 31476799 = 31476908
181 + 31476727 = 31476908
277 + 31476631 = 31476908
409 + 31476499 = 31476908
457 + 31476451 = 31476908

Showing the first eight; more decompositions exist.
