Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669450, here are decompositions:

3 + 8669447 = 8669450
7 + 8669443 = 8669450
61 + 8669389 = 8669450
109 + 8669341 = 8669450
157 + 8669293 = 8669450
199 + 8669251 = 8669450
211 + 8669239 = 8669450
271 + 8669179 = 8669450

Showing the first eight; more decompositions exist.
