Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476918, here are decompositions:

37 + 31476881 = 31476918
47 + 31476871 = 31476918
71 + 31476847 = 31476918
89 + 31476829 = 31476918
97 + 31476821 = 31476918
191 + 31476727 = 31476918
227 + 31476691 = 31476918
307 + 31476611 = 31476918

Showing the first eight; more decompositions exist.
