Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514266, here are decompositions:

5 + 31514261 = 31514266
107 + 31514159 = 31514266
389 + 31513877 = 31514266
449 + 31513817 = 31514266
479 + 31513787 = 31514266
557 + 31513709 = 31514266
569 + 31513697 = 31514266
599 + 31513667 = 31514266

Showing the first eight; more decompositions exist.
