Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18304, here are decompositions:

3 + 18301 = 18304
17 + 18287 = 18304
47 + 18257 = 18304
53 + 18251 = 18304
71 + 18233 = 18304
113 + 18191 = 18304
173 + 18131 = 18304
227 + 18077 = 18304

Showing the first eight; more decompositions exist.
