Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668866, here are decompositions:

29 + 8668837 = 8668866
53 + 8668813 = 8668866
67 + 8668799 = 8668866
83 + 8668783 = 8668866
103 + 8668763 = 8668866
127 + 8668739 = 8668866
179 + 8668687 = 8668866
223 + 8668643 = 8668866

Showing the first eight; more decompositions exist.
