Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509380, here are decompositions:

17 + 509363 = 509380
83 + 509297 = 509380
233 + 509147 = 509380
257 + 509123 = 509380
293 + 509087 = 509380
317 + 509063 = 509380
353 + 509027 = 509380
419 + 508961 = 509380

Showing the first eight; more decompositions exist.
