Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686644, here are decompositions:

157 + 8686487 = 8686644
173 + 8686471 = 8686644
181 + 8686463 = 8686644
223 + 8686421 = 8686644
271 + 8686373 = 8686644
283 + 8686361 = 8686644
331 + 8686313 = 8686644
347 + 8686297 = 8686644

Showing the first eight; more decompositions exist.
