Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655836, here are decompositions:

67 + 8655769 = 8655836
97 + 8655739 = 8655836
103 + 8655733 = 8655836
157 + 8655679 = 8655836
199 + 8655637 = 8655836
379 + 8655457 = 8655836
433 + 8655403 = 8655836
487 + 8655349 = 8655836

Showing the first eight; more decompositions exist.
