Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509512, here are decompositions:

71 + 509441 = 509512
83 + 509429 = 509512
149 + 509363 = 509512
389 + 509123 = 509512
449 + 509063 = 509512
569 + 508943 = 509512
593 + 508919 = 509512
599 + 508913 = 509512

Showing the first eight; more decompositions exist.
