Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457116, here are decompositions:

17 + 31457099 = 31457116
23 + 31457093 = 31457116
107 + 31457009 = 31457116
167 + 31456949 = 31457116
179 + 31456937 = 31457116
233 + 31456883 = 31457116
347 + 31456769 = 31457116
389 + 31456727 = 31457116

Showing the first eight; more decompositions exist.
