Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501580, here are decompositions:

3 + 501577 = 501580
17 + 501563 = 501580
179 + 501401 = 501580
197 + 501383 = 501580
239 + 501341 = 501580
263 + 501317 = 501580
281 + 501299 = 501580
293 + 501287 = 501580

Showing the first eight; more decompositions exist.
