Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618596, here are decompositions:

17 + 31618579 = 31618596
29 + 31618567 = 31618596
47 + 31618549 = 31618596
173 + 31618423 = 31618596
193 + 31618403 = 31618596
277 + 31618319 = 31618596
307 + 31618289 = 31618596
397 + 31618199 = 31618596

Showing the first eight; more decompositions exist.
