Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468716, here are decompositions:

17 + 31468699 = 31468716
79 + 31468637 = 31468716
127 + 31468589 = 31468716
157 + 31468559 = 31468716
163 + 31468553 = 31468716
173 + 31468543 = 31468716
193 + 31468523 = 31468716
199 + 31468517 = 31468716

Showing the first eight; more decompositions exist.
