Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500408, here are decompositions:

19 + 500389 = 500408
67 + 500341 = 500408
109 + 500299 = 500408
151 + 500257 = 500408
199 + 500209 = 500408
211 + 500197 = 500408
229 + 500179 = 500408
241 + 500167 = 500408

Showing the first eight; more decompositions exist.
