Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476956, here are decompositions:

103 + 31476853 = 31476956
109 + 31476847 = 31476956
127 + 31476829 = 31476956
157 + 31476799 = 31476956
223 + 31476733 = 31476956
229 + 31476727 = 31476956
349 + 31476607 = 31476956
409 + 31476547 = 31476956

Showing the first eight; more decompositions exist.
