Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457692, here are decompositions:

5 + 31457687 = 31457692
11 + 31457681 = 31457692
89 + 31457603 = 31457692
179 + 31457513 = 31457692
239 + 31457453 = 31457692
281 + 31457411 = 31457692
389 + 31457303 = 31457692
491 + 31457201 = 31457692

Showing the first eight; more decompositions exist.
