Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514188, here are decompositions:

29 + 31514159 = 31514188
107 + 31514081 = 31514188
311 + 31513877 = 31514188
401 + 31513787 = 31514188
449 + 31513739 = 31514188
467 + 31513721 = 31514188
479 + 31513709 = 31514188
491 + 31513697 = 31514188

Showing the first eight; more decompositions exist.
