Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509542, here are decompositions:

29 + 509513 = 509542
101 + 509441 = 509542
113 + 509429 = 509542
149 + 509393 = 509542
179 + 509363 = 509542
419 + 509123 = 509542
479 + 509063 = 509542
569 + 508973 = 509542

Showing the first eight; more decompositions exist.
