Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617356, here are decompositions:

23 + 8617333 = 8617356
29 + 8617327 = 8617356
37 + 8617319 = 8617356
43 + 8617313 = 8617356
79 + 8617277 = 8617356
103 + 8617253 = 8617356
149 + 8617207 = 8617356
179 + 8617177 = 8617356

Showing the first eight; more decompositions exist.
