Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613810, here are decompositions:

3 + 31613807 = 31613810
13 + 31613797 = 31613810
181 + 31613629 = 31613810
229 + 31613581 = 31613810
271 + 31613539 = 31613810
373 + 31613437 = 31613810
409 + 31613401 = 31613810
433 + 31613377 = 31613810

Showing the first eight; more decompositions exist.
