Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18154, here are decompositions:

5 + 18149 = 18154
11 + 18143 = 18154
23 + 18131 = 18154
107 + 18047 = 18154
113 + 18041 = 18154
167 + 17987 = 18154
173 + 17981 = 18154
197 + 17957 = 18154

Showing the first eight; more decompositions exist.
