Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31314, here are decompositions:

7 + 31307 = 31314
37 + 31277 = 31314
43 + 31271 = 31314
47 + 31267 = 31314
61 + 31253 = 31314
67 + 31247 = 31314
83 + 31231 = 31314
131 + 31183 = 31314

Showing the first eight; more decompositions exist.
