Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669828, here are decompositions:

7 + 8669821 = 8669828
61 + 8669767 = 8669828
127 + 8669701 = 8669828
157 + 8669671 = 8669828
199 + 8669629 = 8669828
439 + 8669389 = 8669828
487 + 8669341 = 8669828
499 + 8669329 = 8669828

Showing the first eight; more decompositions exist.
