Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514, here are decompositions:

3 + 31511 = 31514
37 + 31477 = 31514
127 + 31387 = 31514
157 + 31357 = 31514
181 + 31333 = 31514
193 + 31321 = 31514
277 + 31237 = 31514
283 + 31231 = 31514

Showing the first eight; more decompositions exist.
