Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624918, here are decompositions:

31 + 8624887 = 8624918
37 + 8624881 = 8624918
97 + 8624821 = 8624918
241 + 8624677 = 8624918
607 + 8624311 = 8624918
727 + 8624191 = 8624918
739 + 8624179 = 8624918
787 + 8624131 = 8624918

Showing the first eight; more decompositions exist.
