Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626638, here are decompositions:

17 + 8626621 = 8626638
61 + 8626577 = 8626638
89 + 8626549 = 8626638
109 + 8626529 = 8626638
131 + 8626507 = 8626638
151 + 8626487 = 8626638
179 + 8626459 = 8626638
337 + 8626301 = 8626638

Showing the first eight; more decompositions exist.
