Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18184, here are decompositions:

3 + 18181 = 18184
41 + 18143 = 18184
53 + 18131 = 18184
107 + 18077 = 18184
137 + 18047 = 18184
197 + 17987 = 18184
227 + 17957 = 18184
263 + 17921 = 18184

Showing the first eight; more decompositions exist.
