Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512280, here are decompositions:

11 + 512269 = 512280
29 + 512251 = 512280
31 + 512249 = 512280
73 + 512207 = 512280
113 + 512167 = 512280
179 + 512101 = 512280
233 + 512047 = 512280
269 + 512011 = 512280

Showing the first eight; more decompositions exist.
