Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660766, here are decompositions:

13 + 8660753 = 8660766
19 + 8660747 = 8660766
43 + 8660723 = 8660766
67 + 8660699 = 8660766
73 + 8660693 = 8660766
83 + 8660683 = 8660766
109 + 8660657 = 8660766
113 + 8660653 = 8660766

Showing the first eight; more decompositions exist.
