Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511828, here are decompositions:

17 + 511811 = 511828
41 + 511787 = 511828
71 + 511757 = 511828
137 + 511691 = 511828
197 + 511631 = 511828
269 + 511559 = 511828
389 + 511439 = 511828
419 + 511409 = 511828

Showing the first eight; more decompositions exist.
