Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86266, here are decompositions:

3 + 86263 = 86266
17 + 86249 = 86266
23 + 86243 = 86266
83 + 86183 = 86266
149 + 86117 = 86266
197 + 86069 = 86266
239 + 86027 = 86266
419 + 85847 = 86266

Showing the first eight; more decompositions exist.
