Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691306, here are decompositions:

7 + 8691299 = 8691306
37 + 8691269 = 8691306
59 + 8691247 = 8691306
67 + 8691239 = 8691306
83 + 8691223 = 8691306
97 + 8691209 = 8691306
139 + 8691167 = 8691306
149 + 8691157 = 8691306

Showing the first eight; more decompositions exist.
