Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669466, here are decompositions:

19 + 8669447 = 8669466
23 + 8669443 = 8669466
67 + 8669399 = 8669466
73 + 8669393 = 8669466
137 + 8669329 = 8669466
149 + 8669317 = 8669466
173 + 8669293 = 8669466
227 + 8669239 = 8669466

Showing the first eight; more decompositions exist.
