Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645736, here are decompositions:

7 + 8645729 = 8645736
17 + 8645719 = 8645736
67 + 8645669 = 8645736
79 + 8645657 = 8645736
83 + 8645653 = 8645736
89 + 8645647 = 8645736
103 + 8645633 = 8645736
139 + 8645597 = 8645736

Showing the first eight; more decompositions exist.
