Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669458, here are decompositions:

11 + 8669447 = 8669458
41 + 8669417 = 8669458
47 + 8669411 = 8669458
59 + 8669399 = 8669458
107 + 8669351 = 8669458
179 + 8669279 = 8669458
251 + 8669207 = 8669458
269 + 8669189 = 8669458

Showing the first eight; more decompositions exist.
