Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509508, here are decompositions:

31 + 509477 = 509508
59 + 509449 = 509508
67 + 509441 = 509508
79 + 509429 = 509508
149 + 509359 = 509508
179 + 509329 = 509508
191 + 509317 = 509508
211 + 509297 = 509508

Showing the first eight; more decompositions exist.
