Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457514, here are decompositions:

43 + 31457471 = 31457514
61 + 31457453 = 31457514
103 + 31457411 = 31457514
131 + 31457383 = 31457514
167 + 31457347 = 31457514
173 + 31457341 = 31457514
211 + 31457303 = 31457514
227 + 31457287 = 31457514

Showing the first eight; more decompositions exist.
