Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86500, here are decompositions:

23 + 86477 = 86500
47 + 86453 = 86500
59 + 86441 = 86500
101 + 86399 = 86500
131 + 86369 = 86500
149 + 86351 = 86500
251 + 86249 = 86500
257 + 86243 = 86500

Showing the first eight; more decompositions exist.
