Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514948, here are decompositions:

37 + 31514911 = 31514948
79 + 31514869 = 31514948
109 + 31514839 = 31514948
277 + 31514671 = 31514948
307 + 31514641 = 31514948
349 + 31514599 = 31514948
397 + 31514551 = 31514948
499 + 31514449 = 31514948

Showing the first eight; more decompositions exist.
