Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476942, here are decompositions:

11 + 31476931 = 31476942
61 + 31476881 = 31476942
71 + 31476871 = 31476942
89 + 31476853 = 31476942
113 + 31476829 = 31476942
199 + 31476743 = 31476942
239 + 31476703 = 31476942
251 + 31476691 = 31476942

Showing the first eight; more decompositions exist.
