Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457796, here are decompositions:

37 + 31457759 = 31457796
43 + 31457753 = 31457796
53 + 31457743 = 31457796
59 + 31457737 = 31457796
67 + 31457729 = 31457796
79 + 31457717 = 31457796
89 + 31457707 = 31457796
109 + 31457687 = 31457796

Showing the first eight; more decompositions exist.
