Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593118, here are decompositions:

71 + 31593047 = 31593118
107 + 31593011 = 31593118
197 + 31592921 = 31593118
269 + 31592849 = 31593118
467 + 31592651 = 31593118
587 + 31592531 = 31593118
701 + 31592417 = 31593118
761 + 31592357 = 31593118

Showing the first eight; more decompositions exist.
