Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509218, here are decompositions:

71 + 509147 = 509218
131 + 509087 = 509218
191 + 509027 = 509218
257 + 508961 = 509218
317 + 508901 = 509218
401 + 508817 = 509218
419 + 508799 = 509218
491 + 508727 = 509218

Showing the first eight; more decompositions exist.
