Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18204, here are decompositions:

5 + 18199 = 18204
13 + 18191 = 18204
23 + 18181 = 18204
61 + 18143 = 18204
71 + 18133 = 18204
73 + 18131 = 18204
83 + 18121 = 18204
107 + 18097 = 18204

Showing the first eight; more decompositions exist.
