Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636286, here are decompositions:

17 + 8636269 = 8636286
23 + 8636263 = 8636286
47 + 8636239 = 8636286
67 + 8636219 = 8636286
149 + 8636137 = 8636286
157 + 8636129 = 8636286
163 + 8636123 = 8636286
179 + 8636107 = 8636286

Showing the first eight; more decompositions exist.
