Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486314, here are decompositions:

7 + 31486307 = 31486314
11 + 31486303 = 31486314
31 + 31486283 = 31486314
43 + 31486271 = 31486314
47 + 31486267 = 31486314
61 + 31486253 = 31486314
113 + 31486201 = 31486314
151 + 31486163 = 31486314

Showing the first eight; more decompositions exist.
