Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618410, here are decompositions:

7 + 31618403 = 31618410
113 + 31618297 = 31618410
179 + 31618231 = 31618410
199 + 31618211 = 31618410
211 + 31618199 = 31618410
223 + 31618187 = 31618410
277 + 31618133 = 31618410
283 + 31618127 = 31618410

Showing the first eight; more decompositions exist.
