Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457056, here are decompositions:

5 + 31457051 = 31457056
17 + 31457039 = 31457056
47 + 31457009 = 31457056
107 + 31456949 = 31457056
173 + 31456883 = 31457056
227 + 31456829 = 31457056
269 + 31456787 = 31457056
317 + 31456739 = 31457056

Showing the first eight; more decompositions exist.
