Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644404, here are decompositions:

7 + 8644397 = 8644404
73 + 8644331 = 8644404
103 + 8644301 = 8644404
151 + 8644253 = 8644404
173 + 8644231 = 8644404
191 + 8644213 = 8644404
233 + 8644171 = 8644404
257 + 8644147 = 8644404

Showing the first eight; more decompositions exist.
