Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511956, here are decompositions:

17 + 511939 = 511956
23 + 511933 = 511956
47 + 511909 = 511956
59 + 511897 = 511956
83 + 511873 = 511956
89 + 511867 = 511956
97 + 511859 = 511956
113 + 511843 = 511956

Showing the first eight; more decompositions exist.
