Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514712, here are decompositions:

23 + 31514689 = 31514712
41 + 31514671 = 31514712
59 + 31514653 = 31514712
71 + 31514641 = 31514712
83 + 31514629 = 31514712
113 + 31514599 = 31514712
139 + 31514573 = 31514712
179 + 31514533 = 31514712

Showing the first eight; more decompositions exist.
