Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668806, here are decompositions:

5 + 8668801 = 8668806
7 + 8668799 = 8668806
23 + 8668783 = 8668806
43 + 8668763 = 8668806
67 + 8668739 = 8668806
109 + 8668697 = 8668806
163 + 8668643 = 8668806
193 + 8668613 = 8668806

Showing the first eight; more decompositions exist.
