Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614976, here are decompositions:

23 + 31614953 = 31614976
47 + 31614929 = 31614976
137 + 31614839 = 31614976
179 + 31614797 = 31614976
269 + 31614707 = 31614976
389 + 31614587 = 31614976
599 + 31614377 = 31614976
797 + 31614179 = 31614976

Showing the first eight; more decompositions exist.
