Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668764, here are decompositions:

23 + 8668741 = 8668764
43 + 8668721 = 8668764
53 + 8668711 = 8668764
67 + 8668697 = 8668764
127 + 8668637 = 8668764
151 + 8668613 = 8668764
193 + 8668571 = 8668764
211 + 8668553 = 8668764

Showing the first eight; more decompositions exist.
