Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86506, here are decompositions:

5 + 86501 = 86506
29 + 86477 = 86506
53 + 86453 = 86506
83 + 86423 = 86506
107 + 86399 = 86506
137 + 86369 = 86506
149 + 86357 = 86506
257 + 86249 = 86506

Showing the first eight; more decompositions exist.
