Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691366, here are decompositions:

7 + 8691359 = 8691366
53 + 8691313 = 8691366
67 + 8691299 = 8691366
97 + 8691269 = 8691366
127 + 8691239 = 8691366
137 + 8691229 = 8691366
157 + 8691209 = 8691366
179 + 8691187 = 8691366

Showing the first eight; more decompositions exist.
