Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626566, here are decompositions:

17 + 8626549 = 8626566
37 + 8626529 = 8626566
59 + 8626507 = 8626566
73 + 8626493 = 8626566
79 + 8626487 = 8626566
97 + 8626469 = 8626566
107 + 8626459 = 8626566
149 + 8626417 = 8626566

Showing the first eight; more decompositions exist.
