Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613876, here are decompositions:

37 + 31613839 = 31613876
43 + 31613833 = 31613876
79 + 31613797 = 31613876
157 + 31613719 = 31613876
337 + 31613539 = 31613876
439 + 31613437 = 31613876
499 + 31613377 = 31613876
733 + 31613143 = 31613876

Showing the first eight; more decompositions exist.
