Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618616, here are decompositions:

19 + 31618597 = 31618616
37 + 31618579 = 31618616
67 + 31618549 = 31618616
97 + 31618519 = 31618616
193 + 31618423 = 31618616
613 + 31618003 = 31618616
619 + 31617997 = 31618616
727 + 31617889 = 31618616

Showing the first eight; more decompositions exist.
