Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613846, here are decompositions:

3 + 31613843 = 31613846
7 + 31613839 = 31613846
13 + 31613833 = 31613846
127 + 31613719 = 31613846
223 + 31613623 = 31613846
307 + 31613539 = 31613846
409 + 31613437 = 31613846
463 + 31613383 = 31613846

Showing the first eight; more decompositions exist.
