Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688436, here are decompositions:

83 + 8688353 = 8688436
137 + 8688299 = 8688436
149 + 8688287 = 8688436
227 + 8688209 = 8688436
233 + 8688203 = 8688436
269 + 8688167 = 8688436
293 + 8688143 = 8688436
353 + 8688083 = 8688436

Showing the first eight; more decompositions exist.
