Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624680, here are decompositions:

3 + 8624677 = 8624680
11 + 8624669 = 8624680
47 + 8624633 = 8624680
59 + 8624621 = 8624680
107 + 8624573 = 8624680
173 + 8624507 = 8624680
353 + 8624327 = 8624680
431 + 8624249 = 8624680

Showing the first eight; more decompositions exist.
