Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655984, here are decompositions:

17 + 8655967 = 8655984
31 + 8655953 = 8655984
47 + 8655937 = 8655984
61 + 8655923 = 8655984
67 + 8655917 = 8655984
83 + 8655901 = 8655984
101 + 8655883 = 8655984
107 + 8655877 = 8655984

Showing the first eight; more decompositions exist.
