Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509984, here are decompositions:

37 + 509947 = 509984
73 + 509911 = 509984
151 + 509833 = 509984
331 + 509653 = 509984
337 + 509647 = 509984
421 + 509563 = 509984
463 + 509521 = 509984
571 + 509413 = 509984

Showing the first eight; more decompositions exist.
