Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626686, here are decompositions:

17 + 8626669 = 8626686
43 + 8626643 = 8626686
73 + 8626613 = 8626686
83 + 8626603 = 8626686
109 + 8626577 = 8626686
137 + 8626549 = 8626686
157 + 8626529 = 8626686
179 + 8626507 = 8626686

Showing the first eight; more decompositions exist.
