Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655938, here are decompositions:

19 + 8655919 = 8655938
37 + 8655901 = 8655938
61 + 8655877 = 8655938
79 + 8655859 = 8655938
97 + 8655841 = 8655938
199 + 8655739 = 8655938
307 + 8655631 = 8655938
607 + 8655331 = 8655938

Showing the first eight; more decompositions exist.
