Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688224, here are decompositions:

3 + 8688221 = 8688224
67 + 8688157 = 8688224
157 + 8688067 = 8688224
211 + 8688013 = 8688224
241 + 8687983 = 8688224
271 + 8687953 = 8688224
313 + 8687911 = 8688224
397 + 8687827 = 8688224

Showing the first eight; more decompositions exist.
