Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655944, here are decompositions:

7 + 8655937 = 8655944
43 + 8655901 = 8655944
61 + 8655883 = 8655944
67 + 8655877 = 8655944
103 + 8655841 = 8655944
211 + 8655733 = 8655944
223 + 8655721 = 8655944
307 + 8655637 = 8655944

Showing the first eight; more decompositions exist.
