Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668728, here are decompositions:

7 + 8668721 = 8668728
17 + 8668711 = 8668728
31 + 8668697 = 8668728
41 + 8668687 = 8668728
151 + 8668577 = 8668728
157 + 8668571 = 8668728
179 + 8668549 = 8668728
181 + 8668547 = 8668728

Showing the first eight; more decompositions exist.
