Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691318, here are decompositions:

5 + 8691313 = 8691318
19 + 8691299 = 8691318
37 + 8691281 = 8691318
67 + 8691251 = 8691318
71 + 8691247 = 8691318
79 + 8691239 = 8691318
89 + 8691229 = 8691318
107 + 8691211 = 8691318

Showing the first eight; more decompositions exist.
