Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511914, here are decompositions:

5 + 511909 = 511914
17 + 511897 = 511914
23 + 511891 = 511914
41 + 511873 = 511914
47 + 511867 = 511914
71 + 511843 = 511914
83 + 511831 = 511914
103 + 511811 = 511914

Showing the first eight; more decompositions exist.
