Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613612, here are decompositions:

31 + 31613581 = 31613612
61 + 31613551 = 31613612
73 + 31613539 = 31613612
211 + 31613401 = 31613612
229 + 31613383 = 31613612
271 + 31613341 = 31613612
421 + 31613191 = 31613612
631 + 31612981 = 31613612

Showing the first eight; more decompositions exist.
