Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511952, here are decompositions:

13 + 511939 = 511952
19 + 511933 = 511952
43 + 511909 = 511952
61 + 511891 = 511952
79 + 511873 = 511952
109 + 511843 = 511952
151 + 511801 = 511952
229 + 511723 = 511952

Showing the first eight; more decompositions exist.
