Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659866, here are decompositions:

29 + 8659837 = 8659866
73 + 8659793 = 8659866
97 + 8659769 = 8659866
197 + 8659669 = 8659866
199 + 8659667 = 8659866
223 + 8659643 = 8659866
239 + 8659627 = 8659866
277 + 8659589 = 8659866

Showing the first eight; more decompositions exist.
