Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514906, here are decompositions:

13 + 31514893 = 31514906
37 + 31514869 = 31514906
67 + 31514839 = 31514906
277 + 31514629 = 31514906
307 + 31514599 = 31514906
373 + 31514533 = 31514906
433 + 31514473 = 31514906
457 + 31514449 = 31514906

Showing the first eight; more decompositions exist.
