Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514726, here are decompositions:

37 + 31514689 = 31514726
73 + 31514653 = 31514726
97 + 31514629 = 31514726
127 + 31514599 = 31514726
193 + 31514533 = 31514726
277 + 31514449 = 31514726
307 + 31514419 = 31514726
487 + 31514239 = 31514726

Showing the first eight; more decompositions exist.
