Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669540, here are decompositions:

13 + 8669527 = 8669540
97 + 8669443 = 8669540
151 + 8669389 = 8669540
199 + 8669341 = 8669540
211 + 8669329 = 8669540
223 + 8669317 = 8669540
307 + 8669233 = 8669540
433 + 8669107 = 8669540

Showing the first eight; more decompositions exist.
