Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514670, here are decompositions:

7 + 31514663 = 31514670
17 + 31514653 = 31514670
29 + 31514641 = 31514670
41 + 31514629 = 31514670
43 + 31514627 = 31514670
71 + 31514599 = 31514670
97 + 31514573 = 31514670
137 + 31514533 = 31514670

Showing the first eight; more decompositions exist.
