Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669206, here are decompositions:

17 + 8669189 = 8669206
47 + 8669159 = 8669206
83 + 8669123 = 8669206
89 + 8669117 = 8669206
179 + 8669027 = 8669206
233 + 8668973 = 8669206
239 + 8668967 = 8669206
317 + 8668889 = 8669206

Showing the first eight; more decompositions exist.
