Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501658, here are decompositions:

41 + 501617 = 501658
239 + 501419 = 501658
257 + 501401 = 501658
317 + 501341 = 501658
359 + 501299 = 501658
401 + 501257 = 501658
449 + 501209 = 501658
461 + 501197 = 501658

Showing the first eight; more decompositions exist.
