Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618634, here are decompositions:

13 + 31618621 = 31618634
37 + 31618597 = 31618634
67 + 31618567 = 31618634
193 + 31618441 = 31618634
211 + 31618423 = 31618634
337 + 31618297 = 31618634
571 + 31618063 = 31618634
577 + 31618057 = 31618634

Showing the first eight; more decompositions exist.
