Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468650, here are decompositions:

13 + 31468637 = 31468650
19 + 31468631 = 31468650
53 + 31468597 = 31468650
61 + 31468589 = 31468650
79 + 31468571 = 31468650
97 + 31468553 = 31468650
107 + 31468543 = 31468650
127 + 31468523 = 31468650

Showing the first eight; more decompositions exist.
