Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537314, here are decompositions:

5 + 31537309 = 31537314
7 + 31537307 = 31537314
41 + 31537273 = 31537314
43 + 31537271 = 31537314
47 + 31537267 = 31537314
71 + 31537243 = 31537314
113 + 31537201 = 31537314
163 + 31537151 = 31537314

Showing the first eight; more decompositions exist.
