Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505492, here are decompositions:

11 + 505481 = 505492
23 + 505469 = 505492
83 + 505409 = 505492
173 + 505319 = 505492
179 + 505313 = 505492
191 + 505301 = 505492
311 + 505181 = 505492
353 + 505139 = 505492

Showing the first eight; more decompositions exist.
