Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185450, here are decompositions:

79 + 185371 = 185450
127 + 185323 = 185450
151 + 185299 = 185450
229 + 185221 = 185450
283 + 185167 = 185450
313 + 185137 = 185450
373 + 185077 = 185450
379 + 185071 = 185450

Showing the first eight; more decompositions exist.
