Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669638, here are decompositions:

11 + 8669627 = 8669638
17 + 8669621 = 8669638
137 + 8669501 = 8669638
149 + 8669489 = 8669638
191 + 8669447 = 8669638
227 + 8669411 = 8669638
239 + 8669399 = 8669638
359 + 8669279 = 8669638

Showing the first eight; more decompositions exist.
