Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509538, here are decompositions:

17 + 509521 = 509538
61 + 509477 = 509538
89 + 509449 = 509538
97 + 509441 = 509538
109 + 509429 = 509538
149 + 509389 = 509538
179 + 509359 = 509538
241 + 509297 = 509538

Showing the first eight; more decompositions exist.
