Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514750, here are decompositions:

19 + 31514731 = 31514750
61 + 31514689 = 31514750
79 + 31514671 = 31514750
97 + 31514653 = 31514750
109 + 31514641 = 31514750
151 + 31514599 = 31514750
199 + 31514551 = 31514750
271 + 31514479 = 31514750

Showing the first eight; more decompositions exist.
