Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514612, here are decompositions:

13 + 31514599 = 31514612
61 + 31514551 = 31514612
79 + 31514533 = 31514612
139 + 31514473 = 31514612
163 + 31514449 = 31514612
193 + 31514419 = 31514612
211 + 31514401 = 31514612
373 + 31514239 = 31514612

Showing the first eight; more decompositions exist.
