Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666948, here are decompositions:

67 + 8666881 = 8666948
109 + 8666839 = 8666948
139 + 8666809 = 8666948
151 + 8666797 = 8666948
181 + 8666767 = 8666948
457 + 8666491 = 8666948
601 + 8666347 = 8666948
811 + 8666137 = 8666948

Showing the first eight; more decompositions exist.
