Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645676, here are decompositions:

7 + 8645669 = 8645676
19 + 8645657 = 8645676
23 + 8645653 = 8645676
29 + 8645647 = 8645676
43 + 8645633 = 8645676
59 + 8645617 = 8645676
79 + 8645597 = 8645676
89 + 8645587 = 8645676

Showing the first eight; more decompositions exist.
