Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511180, here are decompositions:

3 + 511177 = 511180
11 + 511169 = 511180
17 + 511163 = 511180
29 + 511151 = 511180
71 + 511109 = 511180
167 + 511013 = 511180
179 + 511001 = 511180
191 + 510989 = 511180

Showing the first eight; more decompositions exist.
