Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669406, here are decompositions:

7 + 8669399 = 8669406
13 + 8669393 = 8669406
17 + 8669389 = 8669406
73 + 8669333 = 8669406
89 + 8669317 = 8669406
113 + 8669293 = 8669406
127 + 8669279 = 8669406
157 + 8669249 = 8669406

Showing the first eight; more decompositions exist.
