Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624728, here are decompositions:

11 + 8624717 = 8624728
59 + 8624669 = 8624728
107 + 8624621 = 8624728
251 + 8624477 = 8624728
269 + 8624459 = 8624728
401 + 8624327 = 8624728
461 + 8624267 = 8624728
479 + 8624249 = 8624728

Showing the first eight; more decompositions exist.
