Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644908, here are decompositions:

5 + 8644903 = 8644908
47 + 8644861 = 8644908
109 + 8644799 = 8644908
127 + 8644781 = 8644908
137 + 8644771 = 8644908
157 + 8644751 = 8644908
179 + 8644729 = 8644908
229 + 8644679 = 8644908

Showing the first eight; more decompositions exist.
