Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468656, here are decompositions:

19 + 31468637 = 31468656
59 + 31468597 = 31468656
67 + 31468589 = 31468656
83 + 31468573 = 31468656
97 + 31468559 = 31468656
103 + 31468553 = 31468656
113 + 31468543 = 31468656
127 + 31468529 = 31468656

Showing the first eight; more decompositions exist.
