Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688146, here are decompositions:

3 + 8688143 = 8688146
13 + 8688133 = 8688146
37 + 8688109 = 8688146
79 + 8688067 = 8688146
163 + 8687983 = 8688146
193 + 8687953 = 8688146
223 + 8687923 = 8688146
349 + 8687797 = 8688146

Showing the first eight; more decompositions exist.
