Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185318, here are decompositions:

19 + 185299 = 185318
97 + 185221 = 185318
151 + 185167 = 185318
157 + 185161 = 185318
181 + 185137 = 185318
229 + 185089 = 185318
241 + 185077 = 185318
349 + 184969 = 185318

Showing the first eight; more decompositions exist.
