Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644656, here are decompositions:

5 + 8644651 = 8644656
23 + 8644633 = 8644656
47 + 8644609 = 8644656
103 + 8644553 = 8644656
127 + 8644529 = 8644656
149 + 8644507 = 8644656
157 + 8644499 = 8644656
179 + 8644477 = 8644656

Showing the first eight; more decompositions exist.
