Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86918, here are decompositions:

61 + 86857 = 86918
67 + 86851 = 86918
151 + 86767 = 86918
199 + 86719 = 86918
229 + 86689 = 86918
241 + 86677 = 86918
331 + 86587 = 86918
379 + 86539 = 86918

Showing the first eight; more decompositions exist.
