Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509428, here are decompositions:

11 + 509417 = 509428
131 + 509297 = 509428
281 + 509147 = 509428
401 + 509027 = 509428
467 + 508961 = 509428
509 + 508919 = 509428
587 + 508841 = 509428
617 + 508811 = 509428

Showing the first eight; more decompositions exist.
