Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476948, here are decompositions:

17 + 31476931 = 31476948
31 + 31476917 = 31476948
67 + 31476881 = 31476948
101 + 31476847 = 31476948
127 + 31476821 = 31476948
149 + 31476799 = 31476948
257 + 31476691 = 31476948
317 + 31476631 = 31476948

Showing the first eight; more decompositions exist.
