Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496556, here are decompositions:

5 + 31496551 = 31496556
17 + 31496539 = 31496556
19 + 31496537 = 31496556
37 + 31496519 = 31496556
67 + 31496489 = 31496556
107 + 31496449 = 31496556
127 + 31496429 = 31496556
137 + 31496419 = 31496556

Showing the first eight; more decompositions exist.
