Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511766, here are decompositions:

43 + 511723 = 511766
97 + 511669 = 511766
139 + 511627 = 511766
163 + 511603 = 511766
193 + 511573 = 511766
313 + 511453 = 511766
349 + 511417 = 511766
379 + 511387 = 511766

Showing the first eight; more decompositions exist.
