Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514724, here are decompositions:

37 + 31514687 = 31514724
53 + 31514671 = 31514724
61 + 31514663 = 31514724
71 + 31514653 = 31514724
83 + 31514641 = 31514724
97 + 31514627 = 31514724
151 + 31514573 = 31514724
173 + 31514551 = 31514724

Showing the first eight; more decompositions exist.
