Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65438, here are decompositions:

19 + 65419 = 65438
31 + 65407 = 65438
67 + 65371 = 65438
151 + 65287 = 65438
181 + 65257 = 65438
199 + 65239 = 65438
271 + 65167 = 65438
337 + 65101 = 65438

Showing the first eight; more decompositions exist.
