Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514664, here are decompositions:

11 + 31514653 = 31514664
23 + 31514641 = 31514664
37 + 31514627 = 31514664
113 + 31514551 = 31514664
127 + 31514537 = 31514664
131 + 31514533 = 31514664
151 + 31514513 = 31514664
191 + 31514473 = 31514664

Showing the first eight; more decompositions exist.
