Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691316, here are decompositions:

3 + 8691313 = 8691316
17 + 8691299 = 8691316
47 + 8691269 = 8691316
107 + 8691209 = 8691316
149 + 8691167 = 8691316
197 + 8691119 = 8691316
353 + 8690963 = 8691316
449 + 8690867 = 8691316

Showing the first eight; more decompositions exist.
