Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457410, here are decompositions:

107 + 31457303 = 31457410
113 + 31457297 = 31457410
239 + 31457171 = 31457410
251 + 31457159 = 31457410
311 + 31457099 = 31457410
317 + 31457093 = 31457410
359 + 31457051 = 31457410
401 + 31457009 = 31457410

Showing the first eight; more decompositions exist.
