Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86356, here are decompositions:

3 + 86353 = 86356
5 + 86351 = 86356
59 + 86297 = 86356
107 + 86249 = 86356
113 + 86243 = 86356
173 + 86183 = 86356
239 + 86117 = 86356
467 + 85889 = 86356

Showing the first eight; more decompositions exist.
