Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618796, here are decompositions:

19 + 31618777 = 31618796
43 + 31618753 = 31618796
103 + 31618693 = 31618796
127 + 31618669 = 31618796
163 + 31618633 = 31618796
199 + 31618597 = 31618796
229 + 31618567 = 31618796
277 + 31618519 = 31618796

Showing the first eight; more decompositions exist.
