Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644464, here are decompositions:

7 + 8644457 = 8644464
11 + 8644453 = 8644464
13 + 8644451 = 8644464
67 + 8644397 = 8644464
137 + 8644327 = 8644464
163 + 8644301 = 8644464
211 + 8644253 = 8644464
233 + 8644231 = 8644464

Showing the first eight; more decompositions exist.
