Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512144, here are decompositions:

7 + 512137 = 512144
43 + 512101 = 512144
97 + 512047 = 512144
181 + 511963 = 512144
211 + 511933 = 512144
271 + 511873 = 512144
277 + 511867 = 512144
313 + 511831 = 512144

Showing the first eight; more decompositions exist.
