Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531314, here are decompositions:

11 + 31531303 = 31531314
13 + 31531301 = 31531314
41 + 31531273 = 31531314
43 + 31531271 = 31531314
47 + 31531267 = 31531314
53 + 31531261 = 31531314
97 + 31531217 = 31531314
151 + 31531163 = 31531314

Showing the first eight; more decompositions exist.
