Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644416, here are decompositions:

19 + 8644397 = 8644416
89 + 8644327 = 8644416
163 + 8644253 = 8644416
173 + 8644243 = 8644416
229 + 8644187 = 8644416
269 + 8644147 = 8644416
293 + 8644123 = 8644416
359 + 8644057 = 8644416

Showing the first eight; more decompositions exist.
