Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509398, here are decompositions:

5 + 509393 = 509398
101 + 509297 = 509398
251 + 509147 = 509398
311 + 509087 = 509398
467 + 508931 = 509398
479 + 508919 = 509398
557 + 508841 = 509398
587 + 508811 = 509398

Showing the first eight; more decompositions exist.
