Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514810, here are decompositions:

79 + 31514731 = 31514810
139 + 31514671 = 31514810
157 + 31514653 = 31514810
181 + 31514629 = 31514810
211 + 31514599 = 31514810
277 + 31514533 = 31514810
331 + 31514479 = 31514810
337 + 31514473 = 31514810

Showing the first eight; more decompositions exist.
