Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185480, here are decompositions:

3 + 185477 = 185480
13 + 185467 = 185480
79 + 185401 = 185480
109 + 185371 = 185480
157 + 185323 = 185480
181 + 185299 = 185480
313 + 185167 = 185480
331 + 185149 = 185480

Showing the first eight; more decompositions exist.
