Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23420, here are decompositions:

3 + 23417 = 23420
109 + 23311 = 23420
127 + 23293 = 23420
151 + 23269 = 23420
193 + 23227 = 23420
211 + 23209 = 23420
223 + 23197 = 23420
277 + 23143 = 23420

Showing the first eight; more decompositions exist.
