Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457710, here are decompositions:

3 + 31457707 = 31457710
23 + 31457687 = 31457710
29 + 31457681 = 31457710
83 + 31457627 = 31457710
107 + 31457603 = 31457710
197 + 31457513 = 31457710
239 + 31457471 = 31457710
257 + 31457453 = 31457710

Showing the first eight; more decompositions exist.
