Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626886, here are decompositions:

67 + 8626819 = 8626886
109 + 8626777 = 8626886
139 + 8626747 = 8626886
283 + 8626603 = 8626886
337 + 8626549 = 8626886
379 + 8626507 = 8626886
643 + 8626243 = 8626886
727 + 8626159 = 8626886

Showing the first eight; more decompositions exist.
