Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18208, here are decompositions:

17 + 18191 = 18208
59 + 18149 = 18208
89 + 18119 = 18208
131 + 18077 = 18208
149 + 18059 = 18208
167 + 18041 = 18208
227 + 17981 = 18208
251 + 17957 = 18208

Showing the first eight; more decompositions exist.
