Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501568, here are decompositions:

5 + 501563 = 501568
149 + 501419 = 501568
167 + 501401 = 501568
227 + 501341 = 501568
251 + 501317 = 501568
269 + 501299 = 501568
281 + 501287 = 501568
311 + 501257 = 501568

Showing the first eight; more decompositions exist.
