Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18344, here are decompositions:

3 + 18341 = 18344
31 + 18313 = 18344
37 + 18307 = 18344
43 + 18301 = 18344
127 + 18217 = 18344
163 + 18181 = 18344
211 + 18133 = 18344
223 + 18121 = 18344

Showing the first eight; more decompositions exist.
