Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669428, here are decompositions:

11 + 8669417 = 8669428
17 + 8669411 = 8669428
29 + 8669399 = 8669428
149 + 8669279 = 8669428
179 + 8669249 = 8669428
191 + 8669237 = 8669428
239 + 8669189 = 8669428
269 + 8669159 = 8669428

Showing the first eight; more decompositions exist.
