Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624528, here are decompositions:

79 + 8624449 = 8624528
277 + 8624251 = 8624528
307 + 8624221 = 8624528
337 + 8624191 = 8624528
349 + 8624179 = 8624528
397 + 8624131 = 8624528
631 + 8623897 = 8624528
727 + 8623801 = 8624528

Showing the first eight; more decompositions exist.
