Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666994, here are decompositions:

5 + 8666989 = 8666994
41 + 8666953 = 8666994
67 + 8666927 = 8666994
103 + 8666891 = 8666994
113 + 8666881 = 8666994
131 + 8666863 = 8666994
197 + 8666797 = 8666994
211 + 8666783 = 8666994

Showing the first eight; more decompositions exist.
