Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511426, here are decompositions:

17 + 511409 = 511426
89 + 511337 = 511426
137 + 511289 = 511426
233 + 511193 = 511426
257 + 511169 = 511426
263 + 511163 = 511426
317 + 511109 = 511426
599 + 510827 = 511426

Showing the first eight; more decompositions exist.
