Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671356, here are decompositions:

17 + 8671339 = 8671356
107 + 8671249 = 8671356
137 + 8671219 = 8671356
163 + 8671193 = 8671356
179 + 8671177 = 8671356
223 + 8671133 = 8671356
229 + 8671127 = 8671356
257 + 8671099 = 8671356

Showing the first eight; more decompositions exist.
