Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511946, here are decompositions:

7 + 511939 = 511946
13 + 511933 = 511946
37 + 511909 = 511946
73 + 511873 = 511946
79 + 511867 = 511946
103 + 511843 = 511946
223 + 511723 = 511946
277 + 511669 = 511946

Showing the first eight; more decompositions exist.
