Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185522, here are decompositions:

3 + 185519 = 185522
31 + 185491 = 185522
151 + 185371 = 185522
163 + 185359 = 185522
199 + 185323 = 185522
223 + 185299 = 185522
373 + 185149 = 185522
433 + 185089 = 185522

Showing the first eight; more decompositions exist.
