Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645694, here are decompositions:

7 + 8645687 = 8645694
37 + 8645657 = 8645694
41 + 8645653 = 8645694
47 + 8645647 = 8645694
61 + 8645633 = 8645694
97 + 8645597 = 8645694
107 + 8645587 = 8645694
151 + 8645543 = 8645694

Showing the first eight; more decompositions exist.
