Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511824, here are decompositions:

13 + 511811 = 511824
23 + 511801 = 511824
31 + 511793 = 511824
37 + 511787 = 511824
67 + 511757 = 511824
101 + 511723 = 511824
113 + 511711 = 511824
191 + 511633 = 511824

Showing the first eight; more decompositions exist.
