Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644726, here are decompositions:

3 + 8644723 = 8644726
23 + 8644703 = 8644726
47 + 8644679 = 8644726
173 + 8644553 = 8644726
197 + 8644529 = 8644726
227 + 8644499 = 8644726
269 + 8644457 = 8644726
569 + 8644157 = 8644726

Showing the first eight; more decompositions exist.
