Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475794, here are decompositions:

17 + 31475777 = 31475794
23 + 31475771 = 31475794
113 + 31475681 = 31475794
197 + 31475597 = 31475794
401 + 31475393 = 31475794
563 + 31475231 = 31475794
653 + 31475141 = 31475794
683 + 31475111 = 31475794

Showing the first eight; more decompositions exist.
