Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644576, here are decompositions:

23 + 8644553 = 8644576
47 + 8644529 = 8644576
137 + 8644439 = 8644576
179 + 8644397 = 8644576
389 + 8644187 = 8644576
419 + 8644157 = 8644576
557 + 8644019 = 8644576
617 + 8643959 = 8644576

Showing the first eight; more decompositions exist.
