Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669680, here are decompositions:

11 + 8669669 = 8669680
23 + 8669657 = 8669680
29 + 8669651 = 8669680
53 + 8669627 = 8669680
59 + 8669621 = 8669680
137 + 8669543 = 8669680
167 + 8669513 = 8669680
179 + 8669501 = 8669680

Showing the first eight; more decompositions exist.
