Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514310, here are decompositions:

13 + 31514297 = 31514310
19 + 31514291 = 31514310
43 + 31514267 = 31514310
71 + 31514239 = 31514310
89 + 31514221 = 31514310
151 + 31514159 = 31514310
167 + 31514143 = 31514310
197 + 31514113 = 31514310

Showing the first eight; more decompositions exist.
