Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86650, here are decompositions:

23 + 86627 = 86650
71 + 86579 = 86650
89 + 86561 = 86650
149 + 86501 = 86650
173 + 86477 = 86650
197 + 86453 = 86650
227 + 86423 = 86650
251 + 86399 = 86650

Showing the first eight; more decompositions exist.
