Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644522, here are decompositions:

11 + 8644511 = 8644522
23 + 8644499 = 8644522
71 + 8644451 = 8644522
83 + 8644439 = 8644522
191 + 8644331 = 8644522
269 + 8644253 = 8644522
431 + 8644091 = 8644522
461 + 8644061 = 8644522

Showing the first eight; more decompositions exist.
