Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21344, here are decompositions:

3 + 21341 = 21344
31 + 21313 = 21344
61 + 21283 = 21344
67 + 21277 = 21344
97 + 21247 = 21344
151 + 21193 = 21344
157 + 21187 = 21344
181 + 21163 = 21344

Showing the first eight; more decompositions exist.
