Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511762, here are decompositions:

5 + 511757 = 511762
59 + 511703 = 511762
71 + 511691 = 511762
131 + 511631 = 511762
179 + 511583 = 511762
239 + 511523 = 511762
353 + 511409 = 511762
401 + 511361 = 511762

Showing the first eight; more decompositions exist.
