Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668964, here are decompositions:

13 + 8668951 = 8668964
67 + 8668897 = 8668964
127 + 8668837 = 8668964
151 + 8668813 = 8668964
163 + 8668801 = 8668964
181 + 8668783 = 8668964
223 + 8668741 = 8668964
277 + 8668687 = 8668964

Showing the first eight; more decompositions exist.
