Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644950, here are decompositions:

23 + 8644927 = 8644950
31 + 8644919 = 8644950
37 + 8644913 = 8644950
47 + 8644903 = 8644950
89 + 8644861 = 8644950
107 + 8644843 = 8644950
151 + 8644799 = 8644950
179 + 8644771 = 8644950

Showing the first eight; more decompositions exist.
