Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86438, here are decompositions:

67 + 86371 = 86438
97 + 86341 = 86438
127 + 86311 = 86438
151 + 86287 = 86438
181 + 86257 = 86438
199 + 86239 = 86438
229 + 86209 = 86438
241 + 86197 = 86438

Showing the first eight; more decompositions exist.
