Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86250, here are decompositions:

7 + 86243 = 86250
11 + 86239 = 86250
41 + 86209 = 86250
53 + 86197 = 86250
67 + 86183 = 86250
71 + 86179 = 86250
79 + 86171 = 86250
89 + 86161 = 86250

Showing the first eight; more decompositions exist.
