Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511678, here are decompositions:

47 + 511631 = 511678
137 + 511541 = 511678
191 + 511487 = 511678
239 + 511439 = 511678
269 + 511409 = 511678
317 + 511361 = 511678
389 + 511289 = 511678
467 + 511211 = 511678

Showing the first eight; more decompositions exist.
