Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86836, here are decompositions:

23 + 86813 = 86836
53 + 86783 = 86836
83 + 86753 = 86836
107 + 86729 = 86836
257 + 86579 = 86836
263 + 86573 = 86836
359 + 86477 = 86836
383 + 86453 = 86836

Showing the first eight; more decompositions exist.
