Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457074, here are decompositions:

3 + 31457071 = 31457074
23 + 31457051 = 31457074
137 + 31456937 = 31457074
191 + 31456883 = 31457074
293 + 31456781 = 31457074
347 + 31456727 = 31457074
353 + 31456721 = 31457074
557 + 31456517 = 31457074

Showing the first eight; more decompositions exist.
