Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65420, here are decompositions:

7 + 65413 = 65420
13 + 65407 = 65420
67 + 65353 = 65420
97 + 65323 = 65420
127 + 65293 = 65420
151 + 65269 = 65420
163 + 65257 = 65420
181 + 65239 = 65420

Showing the first eight; more decompositions exist.
