Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639958, here are decompositions:

7 + 8639951 = 8639958
37 + 8639921 = 8639958
59 + 8639899 = 8639958
109 + 8639849 = 8639958
139 + 8639819 = 8639958
149 + 8639809 = 8639958
179 + 8639779 = 8639958
211 + 8639747 = 8639958

Showing the first eight; more decompositions exist.
