Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669880, here are decompositions:

19 + 8669861 = 8669880
59 + 8669821 = 8669880
103 + 8669777 = 8669880
113 + 8669767 = 8669880
179 + 8669701 = 8669880
211 + 8669669 = 8669880
223 + 8669657 = 8669880
229 + 8669651 = 8669880

Showing the first eight; more decompositions exist.
