Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21314, here are decompositions:

31 + 21283 = 21314
37 + 21277 = 21314
67 + 21247 = 21314
103 + 21211 = 21314
127 + 21187 = 21314
151 + 21163 = 21314
157 + 21157 = 21314
193 + 21121 = 21314

Showing the first eight; more decompositions exist.
