Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477082, here are decompositions:

3 + 31477079 = 31477082
19 + 31477063 = 31477082
31 + 31477051 = 31477082
61 + 31477021 = 31477082
151 + 31476931 = 31477082
211 + 31476871 = 31477082
229 + 31476853 = 31477082
283 + 31476799 = 31477082

Showing the first eight; more decompositions exist.
