Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468680, here are decompositions:

13 + 31468667 = 31468680
43 + 31468637 = 31468680
83 + 31468597 = 31468680
107 + 31468573 = 31468680
109 + 31468571 = 31468680
127 + 31468553 = 31468680
137 + 31468543 = 31468680
151 + 31468529 = 31468680

Showing the first eight; more decompositions exist.
