Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644736, here are decompositions:

7 + 8644729 = 8644736
13 + 8644723 = 8644736
103 + 8644633 = 8644736
127 + 8644609 = 8644736
229 + 8644507 = 8644736
283 + 8644453 = 8644736
409 + 8644327 = 8644736
523 + 8644213 = 8644736

Showing the first eight; more decompositions exist.
