Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513654, here are decompositions:

41 + 31513613 = 31513654
47 + 31513607 = 31513654
251 + 31513403 = 31513654
281 + 31513373 = 31513654
461 + 31513193 = 31513654
467 + 31513187 = 31513654
563 + 31513091 = 31513654
617 + 31513037 = 31513654

Showing the first eight; more decompositions exist.
