Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691198, here are decompositions:

11 + 8691187 = 8691198
31 + 8691167 = 8691198
41 + 8691157 = 8691198
71 + 8691127 = 8691198
79 + 8691119 = 8691198
97 + 8691101 = 8691198
107 + 8691091 = 8691198
179 + 8691019 = 8691198

Showing the first eight; more decompositions exist.
