Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476668, here are decompositions:

37 + 31476631 = 31476668
61 + 31476607 = 31476668
151 + 31476517 = 31476668
211 + 31476457 = 31476668
277 + 31476391 = 31476668
499 + 31476169 = 31476668
571 + 31476097 = 31476668
739 + 31475929 = 31476668

Showing the first eight; more decompositions exist.
