Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669356, here are decompositions:

5 + 8669351 = 8669356
23 + 8669333 = 8669356
107 + 8669249 = 8669356
149 + 8669207 = 8669356
167 + 8669189 = 8669356
197 + 8669159 = 8669356
233 + 8669123 = 8669356
239 + 8669117 = 8669356

Showing the first eight; more decompositions exist.
