Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613588, here are decompositions:

7 + 31613581 = 31613588
37 + 31613551 = 31613588
151 + 31613437 = 31613588
211 + 31613377 = 31613588
397 + 31613191 = 31613588
607 + 31612981 = 31613588
619 + 31612969 = 31613588
757 + 31612831 = 31613588

Showing the first eight; more decompositions exist.
