Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655908, here are decompositions:

7 + 8655901 = 8655908
31 + 8655877 = 8655908
67 + 8655841 = 8655908
139 + 8655769 = 8655908
229 + 8655679 = 8655908
271 + 8655637 = 8655908
277 + 8655631 = 8655908
487 + 8655421 = 8655908

Showing the first eight; more decompositions exist.
