Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501550, here are decompositions:

47 + 501503 = 501550
131 + 501419 = 501550
149 + 501401 = 501550
167 + 501383 = 501550
233 + 501317 = 501550
251 + 501299 = 501550
263 + 501287 = 501550
293 + 501257 = 501550

Showing the first eight; more decompositions exist.
