Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511152, here are decompositions:

29 + 511123 = 511152
41 + 511111 = 511152
43 + 511109 = 511152
113 + 511039 = 511152
139 + 511013 = 511152
151 + 511001 = 511152
163 + 510989 = 511152
211 + 510941 = 511152

Showing the first eight; more decompositions exist.
