Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666946, here are decompositions:

7 + 8666939 = 8666946
19 + 8666927 = 8666946
83 + 8666863 = 8666946
97 + 8666849 = 8666946
107 + 8666839 = 8666946
137 + 8666809 = 8666946
139 + 8666807 = 8666946
149 + 8666797 = 8666946

Showing the first eight; more decompositions exist.
