Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624724, here are decompositions:

7 + 8624717 = 8624724
11 + 8624713 = 8624724
47 + 8624677 = 8624724
103 + 8624621 = 8624724
107 + 8624617 = 8624724
151 + 8624573 = 8624724
331 + 8624393 = 8624724
397 + 8624327 = 8624724

Showing the first eight; more decompositions exist.
