Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509426, here are decompositions:

13 + 509413 = 509426
37 + 509389 = 509426
67 + 509359 = 509426
97 + 509329 = 509426
109 + 509317 = 509426
139 + 509287 = 509426
163 + 509263 = 509426
199 + 509227 = 509426

Showing the first eight; more decompositions exist.
