Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501508, here are decompositions:

5 + 501503 = 501508
89 + 501419 = 501508
107 + 501401 = 501508
167 + 501341 = 501508
191 + 501317 = 501508
251 + 501257 = 501508
311 + 501197 = 501508
317 + 501191 = 501508

Showing the first eight; more decompositions exist.
