Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688164, here are decompositions:

3 + 8688161 = 8688164
7 + 8688157 = 8688164
31 + 8688133 = 8688164
97 + 8688067 = 8688164
151 + 8688013 = 8688164
181 + 8687983 = 8688164
211 + 8687953 = 8688164
241 + 8687923 = 8688164

Showing the first eight; more decompositions exist.
