Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626718, here are decompositions:

19 + 8626699 = 8626718
97 + 8626621 = 8626718
211 + 8626507 = 8626718
421 + 8626297 = 8626718
577 + 8626141 = 8626718
619 + 8626099 = 8626718
739 + 8625979 = 8626718
757 + 8625961 = 8626718

Showing the first eight; more decompositions exist.
