Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644896, here are decompositions:

23 + 8644873 = 8644896
53 + 8644843 = 8644896
97 + 8644799 = 8644896
167 + 8644729 = 8644896
173 + 8644723 = 8644896
193 + 8644703 = 8644896
263 + 8644633 = 8644896
367 + 8644529 = 8644896

Showing the first eight; more decompositions exist.
