Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509290, here are decompositions:

3 + 509287 = 509290
167 + 509123 = 509290
227 + 509063 = 509290
263 + 509027 = 509290
317 + 508973 = 509290
347 + 508943 = 509290
359 + 508931 = 509290
389 + 508901 = 509290

Showing the first eight; more decompositions exist.
