Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468764, here are decompositions:

7 + 31468757 = 31468764
37 + 31468727 = 31468764
97 + 31468667 = 31468764
127 + 31468637 = 31468764
167 + 31468597 = 31468764
191 + 31468573 = 31468764
193 + 31468571 = 31468764
211 + 31468553 = 31468764

Showing the first eight; more decompositions exist.
