Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511776, here are decompositions:

19 + 511757 = 511776
53 + 511723 = 511776
73 + 511703 = 511776
107 + 511669 = 511776
149 + 511627 = 511776
173 + 511603 = 511776
193 + 511583 = 511776
197 + 511579 = 511776

Showing the first eight; more decompositions exist.
