Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505474, here are decompositions:

5 + 505469 = 505474
107 + 505367 = 505474
173 + 505301 = 505474
191 + 505283 = 505474
197 + 505277 = 505474
293 + 505181 = 505474
317 + 505157 = 505474
383 + 505091 = 505474

Showing the first eight; more decompositions exist.
