Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636398, here are decompositions:

11 + 8636387 = 8636398
137 + 8636261 = 8636398
179 + 8636219 = 8636398
257 + 8636141 = 8636398
269 + 8636129 = 8636398
311 + 8636087 = 8636398
317 + 8636081 = 8636398
359 + 8636039 = 8636398

Showing the first eight; more decompositions exist.
