Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509506, here are decompositions:

29 + 509477 = 509506
89 + 509417 = 509506
113 + 509393 = 509506
359 + 509147 = 509506
383 + 509123 = 509506
419 + 509087 = 509506
443 + 509063 = 509506
479 + 509027 = 509506

Showing the first eight; more decompositions exist.
