Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644444, here are decompositions:

5 + 8644439 = 8644444
47 + 8644397 = 8644444
113 + 8644331 = 8644444
191 + 8644253 = 8644444
257 + 8644187 = 8644444
353 + 8644091 = 8644444
383 + 8644061 = 8644444
491 + 8643953 = 8644444

Showing the first eight; more decompositions exist.
