Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690664, here are decompositions:

5 + 8690659 = 8690664
53 + 8690611 = 8690664
61 + 8690603 = 8690664
71 + 8690593 = 8690664
97 + 8690567 = 8690664
107 + 8690557 = 8690664
113 + 8690551 = 8690664
211 + 8690453 = 8690664

Showing the first eight; more decompositions exist.
