Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511378, here are decompositions:

17 + 511361 = 511378
41 + 511337 = 511378
89 + 511289 = 511378
167 + 511211 = 511378
227 + 511151 = 511378
269 + 511109 = 511378
317 + 511061 = 511378
359 + 511019 = 511378

Showing the first eight; more decompositions exist.
