Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689806, here are decompositions:

7 + 8689799 = 8689806
29 + 8689777 = 8689806
53 + 8689753 = 8689806
79 + 8689727 = 8689806
149 + 8689657 = 8689806
157 + 8689649 = 8689806
163 + 8689643 = 8689806
179 + 8689627 = 8689806

Showing the first eight; more decompositions exist.
