Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511950, here are decompositions:

11 + 511939 = 511950
17 + 511933 = 511950
41 + 511909 = 511950
53 + 511897 = 511950
59 + 511891 = 511950
83 + 511867 = 511950
107 + 511843 = 511950
139 + 511811 = 511950

Showing the first eight; more decompositions exist.
