Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639926, here are decompositions:

3 + 8639923 = 8639926
5 + 8639921 = 8639926
17 + 8639909 = 8639926
23 + 8639903 = 8639926
89 + 8639837 = 8639926
107 + 8639819 = 8639926
173 + 8639753 = 8639926
179 + 8639747 = 8639926

Showing the first eight; more decompositions exist.
