Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665764, here are decompositions:

47 + 8665717 = 8665764
61 + 8665703 = 8665764
97 + 8665667 = 8665764
113 + 8665651 = 8665764
131 + 8665633 = 8665764
181 + 8665583 = 8665764
193 + 8665571 = 8665764
197 + 8665567 = 8665764

Showing the first eight; more decompositions exist.
