Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655894, here are decompositions:

11 + 8655883 = 8655894
17 + 8655877 = 8655894
53 + 8655841 = 8655894
173 + 8655721 = 8655894
193 + 8655701 = 8655894
223 + 8655671 = 8655894
241 + 8655653 = 8655894
257 + 8655637 = 8655894

Showing the first eight; more decompositions exist.
