Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514556, here are decompositions:

5 + 31514551 = 31514556
19 + 31514537 = 31514556
23 + 31514533 = 31514556
43 + 31514513 = 31514556
79 + 31514477 = 31514556
83 + 31514473 = 31514556
107 + 31514449 = 31514556
127 + 31514429 = 31514556

Showing the first eight; more decompositions exist.
