Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514652, here are decompositions:

11 + 31514641 = 31514652
23 + 31514629 = 31514652
53 + 31514599 = 31514652
73 + 31514579 = 31514652
79 + 31514573 = 31514652
101 + 31514551 = 31514652
139 + 31514513 = 31514652
173 + 31514479 = 31514652

Showing the first eight; more decompositions exist.
