Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457134, here are decompositions:

41 + 31457093 = 31457134
53 + 31457081 = 31457134
83 + 31457051 = 31457134
197 + 31456937 = 31457134
251 + 31456883 = 31457134
347 + 31456787 = 31457134
353 + 31456781 = 31457134
431 + 31456703 = 31457134

Showing the first eight; more decompositions exist.
