Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509392, here are decompositions:

3 + 509389 = 509392
29 + 509363 = 509392
269 + 509123 = 509392
419 + 508973 = 509392
431 + 508961 = 509392
449 + 508943 = 509392
461 + 508931 = 509392
479 + 508913 = 509392

Showing the first eight; more decompositions exist.
