Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185316, here are decompositions:

7 + 185309 = 185316
13 + 185303 = 185316
17 + 185299 = 185316
73 + 185243 = 185316
83 + 185233 = 185316
127 + 185189 = 185316
139 + 185177 = 185316
149 + 185167 = 185316

Showing the first eight; more decompositions exist.
