Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511216, here are decompositions:

3 + 511213 = 511216
5 + 511211 = 511216
23 + 511193 = 511216
47 + 511169 = 511216
53 + 511163 = 511216
107 + 511109 = 511216
197 + 511019 = 511216
227 + 510989 = 511216

Showing the first eight; more decompositions exist.
