Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688432, here are decompositions:

23 + 8688409 = 8688432
79 + 8688353 = 8688432
83 + 8688349 = 8688432
149 + 8688283 = 8688432
173 + 8688259 = 8688432
211 + 8688221 = 8688432
223 + 8688209 = 8688432
229 + 8688203 = 8688432

Showing the first eight; more decompositions exist.
