Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457524, here are decompositions:

11 + 31457513 = 31457524
53 + 31457471 = 31457524
71 + 31457453 = 31457524
113 + 31457411 = 31457524
227 + 31457297 = 31457524
257 + 31457267 = 31457524
353 + 31457171 = 31457524
431 + 31457093 = 31457524

Showing the first eight; more decompositions exist.
