Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672356, here are decompositions:

3 + 8672353 = 8672356
23 + 8672333 = 8672356
59 + 8672297 = 8672356
83 + 8672273 = 8672356
89 + 8672267 = 8672356
149 + 8672207 = 8672356
179 + 8672177 = 8672356
239 + 8672117 = 8672356

Showing the first eight; more decompositions exist.
