Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514658, here are decompositions:

5 + 31514653 = 31514658
17 + 31514641 = 31514658
29 + 31514629 = 31514658
31 + 31514627 = 31514658
59 + 31514599 = 31514658
79 + 31514579 = 31514658
107 + 31514551 = 31514658
179 + 31514479 = 31514658

Showing the first eight; more decompositions exist.
