Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669446, here are decompositions:

3 + 8669443 = 8669446
29 + 8669417 = 8669446
47 + 8669399 = 8669446
53 + 8669393 = 8669446
113 + 8669333 = 8669446
167 + 8669279 = 8669446
197 + 8669249 = 8669446
239 + 8669207 = 8669446

Showing the first eight; more decompositions exist.
