Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626918, here are decompositions:

17 + 8626901 = 8626918
71 + 8626847 = 8626918
107 + 8626811 = 8626918
227 + 8626691 = 8626918
389 + 8626529 = 8626918
401 + 8626517 = 8626918
431 + 8626487 = 8626918
449 + 8626469 = 8626918

Showing the first eight; more decompositions exist.
