Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18288, here are decompositions:

19 + 18269 = 18288
31 + 18257 = 18288
37 + 18251 = 18288
59 + 18229 = 18288
71 + 18217 = 18288
89 + 18199 = 18288
97 + 18191 = 18288
107 + 18181 = 18288

Showing the first eight; more decompositions exist.
