Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514630, here are decompositions:

3 + 31514627 = 31514630
31 + 31514599 = 31514630
79 + 31514551 = 31514630
97 + 31514533 = 31514630
151 + 31514479 = 31514630
157 + 31514473 = 31514630
181 + 31514449 = 31514630
211 + 31514419 = 31514630

Showing the first eight; more decompositions exist.
