Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672944, here are decompositions:

11 + 8672933 = 8672944
17 + 8672927 = 8672944
47 + 8672897 = 8672944
53 + 8672891 = 8672944
83 + 8672861 = 8672944
113 + 8672831 = 8672944
257 + 8672687 = 8672944
347 + 8672597 = 8672944

Showing the first eight; more decompositions exist.
