Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512318, here are decompositions:

7 + 512311 = 512318
31 + 512287 = 512318
67 + 512251 = 512318
151 + 512167 = 512318
181 + 512137 = 512318
271 + 512047 = 512318
307 + 512011 = 512318
379 + 511939 = 512318

Showing the first eight; more decompositions exist.
