Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476846, here are decompositions:

17 + 31476829 = 31476846
47 + 31476799 = 31476846
103 + 31476743 = 31476846
113 + 31476733 = 31476846
223 + 31476623 = 31476846
239 + 31476607 = 31476846
337 + 31476509 = 31476846
347 + 31476499 = 31476846

Showing the first eight; more decompositions exist.
