Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655800, here are decompositions:

31 + 8655769 = 8655800
61 + 8655739 = 8655800
67 + 8655733 = 8655800
79 + 8655721 = 8655800
151 + 8655649 = 8655800
163 + 8655637 = 8655800
367 + 8655433 = 8655800
379 + 8655421 = 8655800

Showing the first eight; more decompositions exist.
