Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511970, here are decompositions:

7 + 511963 = 511970
31 + 511939 = 511970
37 + 511933 = 511970
61 + 511909 = 511970
73 + 511897 = 511970
79 + 511891 = 511970
97 + 511873 = 511970
103 + 511867 = 511970

Showing the first eight; more decompositions exist.
