Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501538, here are decompositions:

137 + 501401 = 501538
197 + 501341 = 501538
239 + 501299 = 501538
251 + 501287 = 501538
281 + 501257 = 501538
347 + 501191 = 501538
449 + 501089 = 501538
461 + 501077 = 501538

Showing the first eight; more decompositions exist.
