Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476938, here are decompositions:

7 + 31476931 = 31476938
67 + 31476871 = 31476938
109 + 31476829 = 31476938
139 + 31476799 = 31476938
211 + 31476727 = 31476938
307 + 31476631 = 31476938
331 + 31476607 = 31476938
421 + 31476517 = 31476938

Showing the first eight; more decompositions exist.
