Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86510, here are decompositions:

19 + 86491 = 86510
43 + 86467 = 86510
97 + 86413 = 86510
139 + 86371 = 86510
157 + 86353 = 86510
199 + 86311 = 86510
223 + 86287 = 86510
241 + 86269 = 86510

Showing the first eight; more decompositions exist.
