Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185340, here are decompositions:

13 + 185327 = 185340
17 + 185323 = 185340
31 + 185309 = 185340
37 + 185303 = 185340
41 + 185299 = 185340
73 + 185267 = 185340
97 + 185243 = 185340
107 + 185233 = 185340

Showing the first eight; more decompositions exist.
