Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475944, here are decompositions:

131 + 31475813 = 31475944
167 + 31475777 = 31475944
173 + 31475771 = 31475944
263 + 31475681 = 31475944
347 + 31475597 = 31475944
491 + 31475453 = 31475944
557 + 31475387 = 31475944
701 + 31475243 = 31475944

Showing the first eight; more decompositions exist.
