Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509438, here are decompositions:

79 + 509359 = 509438
109 + 509329 = 509438
151 + 509287 = 509438
157 + 509281 = 509438
199 + 509239 = 509438
211 + 509227 = 509438
337 + 509101 = 509438
367 + 509071 = 509438

Showing the first eight; more decompositions exist.
