Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669456, here are decompositions:

13 + 8669443 = 8669456
67 + 8669389 = 8669456
127 + 8669329 = 8669456
139 + 8669317 = 8669456
163 + 8669293 = 8669456
223 + 8669233 = 8669456
277 + 8669179 = 8669456
349 + 8669107 = 8669456

Showing the first eight; more decompositions exist.
