Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644716, here are decompositions:

13 + 8644703 = 8644716
37 + 8644679 = 8644716
83 + 8644633 = 8644716
107 + 8644609 = 8644716
109 + 8644607 = 8644716
163 + 8644553 = 8644716
239 + 8644477 = 8644716
263 + 8644453 = 8644716

Showing the first eight; more decompositions exist.
