Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86522, here are decompositions:

13 + 86509 = 86522
31 + 86491 = 86522
61 + 86461 = 86522
109 + 86413 = 86522
151 + 86371 = 86522
181 + 86341 = 86522
199 + 86323 = 86522
211 + 86311 = 86522

Showing the first eight; more decompositions exist.
