Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691216, here are decompositions:

5 + 8691211 = 8691216
7 + 8691209 = 8691216
29 + 8691187 = 8691216
59 + 8691157 = 8691216
89 + 8691127 = 8691216
97 + 8691119 = 8691216
173 + 8691043 = 8691216
197 + 8691019 = 8691216

Showing the first eight; more decompositions exist.
