Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666826, here are decompositions:

17 + 8666809 = 8666826
19 + 8666807 = 8666826
29 + 8666797 = 8666826
43 + 8666783 = 8666826
53 + 8666773 = 8666826
59 + 8666767 = 8666826
79 + 8666747 = 8666826
199 + 8666627 = 8666826

Showing the first eight; more decompositions exist.
