Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624820, here are decompositions:

13 + 8624807 = 8624820
47 + 8624773 = 8624820
67 + 8624753 = 8624820
103 + 8624717 = 8624820
107 + 8624713 = 8624820
151 + 8624669 = 8624820
199 + 8624621 = 8624820
313 + 8624507 = 8624820

Showing the first eight; more decompositions exist.
