Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509558, here are decompositions:

37 + 509521 = 509558
109 + 509449 = 509558
199 + 509359 = 509558
229 + 509329 = 509558
241 + 509317 = 509558
271 + 509287 = 509558
277 + 509281 = 509558
331 + 509227 = 509558

Showing the first eight; more decompositions exist.
