Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669800, here are decompositions:

23 + 8669777 = 8669800
131 + 8669669 = 8669800
149 + 8669651 = 8669800
173 + 8669627 = 8669800
179 + 8669621 = 8669800
257 + 8669543 = 8669800
311 + 8669489 = 8669800
317 + 8669483 = 8669800

Showing the first eight; more decompositions exist.
