Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645766, here are decompositions:

5 + 8645761 = 8645766
7 + 8645759 = 8645766
37 + 8645729 = 8645766
47 + 8645719 = 8645766
79 + 8645687 = 8645766
97 + 8645669 = 8645766
109 + 8645657 = 8645766
113 + 8645653 = 8645766

Showing the first eight; more decompositions exist.
