Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185304, here are decompositions:

5 + 185299 = 185304
13 + 185291 = 185304
37 + 185267 = 185304
61 + 185243 = 185304
71 + 185233 = 185304
83 + 185221 = 185304
127 + 185177 = 185304
137 + 185167 = 185304

Showing the first eight; more decompositions exist.
