Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644450, here are decompositions:

11 + 8644439 = 8644450
53 + 8644397 = 8644450
149 + 8644301 = 8644450
197 + 8644253 = 8644450
263 + 8644187 = 8644450
293 + 8644157 = 8644450
359 + 8644091 = 8644450
389 + 8644061 = 8644450

Showing the first eight; more decompositions exist.
