Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512156, here are decompositions:

19 + 512137 = 512156
97 + 512059 = 512156
109 + 512047 = 512156
193 + 511963 = 512156
223 + 511933 = 512156
283 + 511873 = 512156
313 + 511843 = 512156
433 + 511723 = 512156

Showing the first eight; more decompositions exist.
