Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509488, here are decompositions:

11 + 509477 = 509488
47 + 509441 = 509488
59 + 509429 = 509488
71 + 509417 = 509488
191 + 509297 = 509488
401 + 509087 = 509488
461 + 509027 = 509488
557 + 508931 = 509488

Showing the first eight; more decompositions exist.
