Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668828, here are decompositions:

11 + 8668817 = 8668828
29 + 8668799 = 8668828
89 + 8668739 = 8668828
107 + 8668721 = 8668828
131 + 8668697 = 8668828
191 + 8668637 = 8668828
251 + 8668577 = 8668828
257 + 8668571 = 8668828

Showing the first eight; more decompositions exist.
