Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628740, here are decompositions:

13 + 8628727 = 8628740
31 + 8628709 = 8628740
79 + 8628661 = 8628740
97 + 8628643 = 8628740
139 + 8628601 = 8628740
193 + 8628547 = 8628740
277 + 8628463 = 8628740
619 + 8628121 = 8628740

Showing the first eight; more decompositions exist.
