Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613086, here are decompositions:

59 + 31613027 = 31613086
173 + 31612913 = 31613086
233 + 31612853 = 31613086
347 + 31612739 = 31613086
353 + 31612733 = 31613086
359 + 31612727 = 31613086
419 + 31612667 = 31613086
467 + 31612619 = 31613086

Showing the first eight; more decompositions exist.
