Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618608, here are decompositions:

11 + 31618597 = 31618608
29 + 31618579 = 31618608
41 + 31618567 = 31618608
59 + 31618549 = 31618608
61 + 31618547 = 31618608
89 + 31618519 = 31618608
167 + 31618441 = 31618608
199 + 31618409 = 31618608

Showing the first eight; more decompositions exist.
