Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666958, here are decompositions:

5 + 8666953 = 8666958
19 + 8666939 = 8666958
31 + 8666927 = 8666958
67 + 8666891 = 8666958
109 + 8666849 = 8666958
149 + 8666809 = 8666958
151 + 8666807 = 8666958
191 + 8666767 = 8666958

Showing the first eight; more decompositions exist.
