Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618670, here are decompositions:

7 + 31618663 = 31618670
37 + 31618633 = 31618670
73 + 31618597 = 31618670
103 + 31618567 = 31618670
151 + 31618519 = 31618670
229 + 31618441 = 31618670
373 + 31618297 = 31618670
439 + 31618231 = 31618670

Showing the first eight; more decompositions exist.
