Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501490, here are decompositions:

71 + 501419 = 501490
89 + 501401 = 501490
107 + 501383 = 501490
149 + 501341 = 501490
173 + 501317 = 501490
191 + 501299 = 501490
233 + 501257 = 501490
257 + 501233 = 501490

Showing the first eight; more decompositions exist.
