Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86540, here are decompositions:

7 + 86533 = 86540
31 + 86509 = 86540
73 + 86467 = 86540
79 + 86461 = 86540
127 + 86413 = 86540
151 + 86389 = 86540
199 + 86341 = 86540
229 + 86311 = 86540

Showing the first eight; more decompositions exist.
