Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618614, here are decompositions:

17 + 31618597 = 31618614
47 + 31618567 = 31618614
67 + 31618547 = 31618614
151 + 31618463 = 31618614
173 + 31618441 = 31618614
191 + 31618423 = 31618614
211 + 31618403 = 31618614
317 + 31618297 = 31618614

Showing the first eight; more decompositions exist.
