Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514610, here are decompositions:

11 + 31514599 = 31514610
31 + 31514579 = 31514610
37 + 31514573 = 31514610
59 + 31514551 = 31514610
73 + 31514537 = 31514610
97 + 31514513 = 31514610
131 + 31514479 = 31514610
137 + 31514473 = 31514610

Showing the first eight; more decompositions exist.
