Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512168, here are decompositions:

31 + 512137 = 512168
67 + 512101 = 512168
109 + 512059 = 512168
157 + 512011 = 512168
229 + 511939 = 512168
271 + 511897 = 512168
277 + 511891 = 512168
337 + 511831 = 512168

Showing the first eight; more decompositions exist.
