Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18448, here are decompositions:

5 + 18443 = 18448
47 + 18401 = 18448
107 + 18341 = 18448
137 + 18311 = 18448
179 + 18269 = 18448
191 + 18257 = 18448
197 + 18251 = 18448
257 + 18191 = 18448

Showing the first eight; more decompositions exist.
