Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644662, here are decompositions:

11 + 8644651 = 8644662
29 + 8644633 = 8644662
53 + 8644609 = 8644662
109 + 8644553 = 8644662
151 + 8644511 = 8644662
163 + 8644499 = 8644662
211 + 8644451 = 8644662
223 + 8644439 = 8644662

Showing the first eight; more decompositions exist.
