Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511168, here are decompositions:

5 + 511163 = 511168
17 + 511151 = 511168
59 + 511109 = 511168
107 + 511061 = 511168
149 + 511019 = 511168
167 + 511001 = 511168
179 + 510989 = 511168
227 + 510941 = 511168

Showing the first eight; more decompositions exist.
