Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618414, here are decompositions:

5 + 31618409 = 31618414
11 + 31618403 = 31618414
53 + 31618361 = 31618414
227 + 31618187 = 31618414
251 + 31618163 = 31618414
281 + 31618133 = 31618414
293 + 31618121 = 31618414
353 + 31618061 = 31618414

Showing the first eight; more decompositions exist.
