Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621944, here are decompositions:

5 + 8621939 = 8621944
11 + 8621933 = 8621944
17 + 8621927 = 8621944
47 + 8621897 = 8621944
83 + 8621861 = 8621944
101 + 8621843 = 8621944
113 + 8621831 = 8621944
197 + 8621747 = 8621944

Showing the first eight; more decompositions exist.
