Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626666, here are decompositions:

23 + 8626643 = 8626666
53 + 8626613 = 8626666
89 + 8626577 = 8626666
137 + 8626529 = 8626666
149 + 8626517 = 8626666
173 + 8626493 = 8626666
179 + 8626487 = 8626666
197 + 8626469 = 8626666

Showing the first eight; more decompositions exist.
