Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511904, here are decompositions:

7 + 511897 = 511904
13 + 511891 = 511904
31 + 511873 = 511904
37 + 511867 = 511904
61 + 511843 = 511904
73 + 511831 = 511904
103 + 511801 = 511904
181 + 511723 = 511904

Showing the first eight; more decompositions exist.
