Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644776, here are decompositions:

5 + 8644771 = 8644776
47 + 8644729 = 8644776
53 + 8644723 = 8644776
73 + 8644703 = 8644776
97 + 8644679 = 8644776
167 + 8644609 = 8644776
223 + 8644553 = 8644776
269 + 8644507 = 8644776

Showing the first eight; more decompositions exist.
