Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185492, here are decompositions:

193 + 185299 = 185492
271 + 185221 = 185492
331 + 185161 = 185492
421 + 185071 = 185492
499 + 184993 = 185492
523 + 184969 = 185492
613 + 184879 = 185492
661 + 184831 = 185492

Showing the first eight; more decompositions exist.
