Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457926, here are decompositions:

23 + 31457903 = 31457926
83 + 31457843 = 31457926
107 + 31457819 = 31457926
167 + 31457759 = 31457926
173 + 31457753 = 31457926
197 + 31457729 = 31457926
239 + 31457687 = 31457926
659 + 31457267 = 31457926

Showing the first eight; more decompositions exist.
