Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624638, here are decompositions:

5 + 8624633 = 8624638
17 + 8624621 = 8624638
131 + 8624507 = 8624638
179 + 8624459 = 8624638
311 + 8624327 = 8624638
389 + 8624249 = 8624638
401 + 8624237 = 8624638
461 + 8624177 = 8624638

Showing the first eight; more decompositions exist.
