Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659806, here are decompositions:

13 + 8659793 = 8659806
37 + 8659769 = 8659806
59 + 8659747 = 8659806
137 + 8659669 = 8659806
139 + 8659667 = 8659806
163 + 8659643 = 8659806
179 + 8659627 = 8659806
263 + 8659543 = 8659806

Showing the first eight; more decompositions exist.
