Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614748, here are decompositions:

41 + 31614707 = 31614748
47 + 31614701 = 31614748
71 + 31614677 = 31614748
101 + 31614647 = 31614748
107 + 31614641 = 31614748
197 + 31614551 = 31614748
521 + 31614227 = 31614748
569 + 31614179 = 31614748

Showing the first eight; more decompositions exist.
