Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669824, here are decompositions:

3 + 8669821 = 8669824
47 + 8669777 = 8669824
167 + 8669657 = 8669824
173 + 8669651 = 8669824
197 + 8669627 = 8669824
281 + 8669543 = 8669824
311 + 8669513 = 8669824
347 + 8669477 = 8669824

Showing the first eight; more decompositions exist.
