Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514708, here are decompositions:

19 + 31514689 = 31514708
37 + 31514671 = 31514708
67 + 31514641 = 31514708
79 + 31514629 = 31514708
109 + 31514599 = 31514708
157 + 31514551 = 31514708
229 + 31514479 = 31514708
307 + 31514401 = 31514708

Showing the first eight; more decompositions exist.
