Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669644, here are decompositions:

17 + 8669627 = 8669644
23 + 8669621 = 8669644
101 + 8669543 = 8669644
131 + 8669513 = 8669644
167 + 8669477 = 8669644
197 + 8669447 = 8669644
227 + 8669417 = 8669644
233 + 8669411 = 8669644

Showing the first eight; more decompositions exist.
