Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644944, here are decompositions:

17 + 8644927 = 8644944
31 + 8644913 = 8644944
41 + 8644903 = 8644944
71 + 8644873 = 8644944
83 + 8644861 = 8644944
101 + 8644843 = 8644944
163 + 8644781 = 8644944
173 + 8644771 = 8644944

Showing the first eight; more decompositions exist.
