Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18144, here are decompositions:

11 + 18133 = 18144
13 + 18131 = 18144
17 + 18127 = 18144
23 + 18121 = 18144
47 + 18097 = 18144
67 + 18077 = 18144
83 + 18061 = 18144
97 + 18047 = 18144

Showing the first eight; more decompositions exist.
