Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86686, here are decompositions:

59 + 86627 = 86686
107 + 86579 = 86686
113 + 86573 = 86686
233 + 86453 = 86686
263 + 86423 = 86686
317 + 86369 = 86686
389 + 86297 = 86686
443 + 86243 = 86686

Showing the first eight; more decompositions exist.
