Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514738, here are decompositions:

7 + 31514731 = 31514738
67 + 31514671 = 31514738
97 + 31514641 = 31514738
109 + 31514629 = 31514738
139 + 31514599 = 31514738
337 + 31514401 = 31514738
499 + 31514239 = 31514738
547 + 31514191 = 31514738

Showing the first eight; more decompositions exist.
