Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688444, here are decompositions:

7 + 8688437 = 8688444
47 + 8688397 = 8688444
157 + 8688287 = 8688444
173 + 8688271 = 8688444
223 + 8688221 = 8688444
241 + 8688203 = 8688444
277 + 8688167 = 8688444
283 + 8688161 = 8688444

Showing the first eight; more decompositions exist.
