Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511754, here are decompositions:

31 + 511723 = 511754
43 + 511711 = 511754
127 + 511627 = 511754
151 + 511603 = 511754
163 + 511591 = 511754
181 + 511573 = 511754
277 + 511477 = 511754
307 + 511447 = 511754

Showing the first eight; more decompositions exist.
