Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669250, here are decompositions:

11 + 8669239 = 8669250
13 + 8669237 = 8669250
17 + 8669233 = 8669250
43 + 8669207 = 8669250
61 + 8669189 = 8669250
71 + 8669179 = 8669250
127 + 8669123 = 8669250
137 + 8669113 = 8669250

Showing the first eight; more decompositions exist.
