Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512148, here are decompositions:

11 + 512137 = 512148
47 + 512101 = 512148
89 + 512059 = 512148
101 + 512047 = 512148
127 + 512021 = 512148
137 + 512011 = 512148
139 + 512009 = 512148
151 + 511997 = 512148

Showing the first eight; more decompositions exist.
