Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665806, here are decompositions:

7 + 8665799 = 8665806
29 + 8665777 = 8665806
89 + 8665717 = 8665806
103 + 8665703 = 8665806
139 + 8665667 = 8665806
157 + 8665649 = 8665806
173 + 8665633 = 8665806
223 + 8665583 = 8665806

Showing the first eight; more decompositions exist.
