Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624866, here are decompositions:

59 + 8624807 = 8624866
113 + 8624753 = 8624866
149 + 8624717 = 8624866
197 + 8624669 = 8624866
233 + 8624633 = 8624866
293 + 8624573 = 8624866
359 + 8624507 = 8624866
389 + 8624477 = 8624866

Showing the first eight; more decompositions exist.
