Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666670, here are decompositions:

43 + 8666627 = 8666670
73 + 8666597 = 8666670
79 + 8666591 = 8666670
127 + 8666543 = 8666670
137 + 8666533 = 8666670
151 + 8666519 = 8666670
157 + 8666513 = 8666670
179 + 8666491 = 8666670

Showing the first eight; more decompositions exist.
