Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669346, here are decompositions:

5 + 8669341 = 8669346
13 + 8669333 = 8669346
17 + 8669329 = 8669346
29 + 8669317 = 8669346
53 + 8669293 = 8669346
67 + 8669279 = 8669346
97 + 8669249 = 8669346
107 + 8669239 = 8669346

Showing the first eight; more decompositions exist.
