Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511944, here are decompositions:

5 + 511939 = 511944
11 + 511933 = 511944
47 + 511897 = 511944
53 + 511891 = 511944
71 + 511873 = 511944
101 + 511843 = 511944
113 + 511831 = 511944
151 + 511793 = 511944

Showing the first eight; more decompositions exist.
