Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185330, here are decompositions:

3 + 185327 = 185330
7 + 185323 = 185330
31 + 185299 = 185330
97 + 185233 = 185330
109 + 185221 = 185330
163 + 185167 = 185330
181 + 185149 = 185330
193 + 185137 = 185330

Showing the first eight; more decompositions exist.
