Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644566, here are decompositions:

13 + 8644553 = 8644566
37 + 8644529 = 8644566
59 + 8644507 = 8644566
67 + 8644499 = 8644566
89 + 8644477 = 8644566
109 + 8644457 = 8644566
113 + 8644453 = 8644566
127 + 8644439 = 8644566

Showing the first eight; more decompositions exist.
