Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511926, here are decompositions:

17 + 511909 = 511926
29 + 511897 = 511926
53 + 511873 = 511926
59 + 511867 = 511926
67 + 511859 = 511926
83 + 511843 = 511926
139 + 511787 = 511926
223 + 511703 = 511926

Showing the first eight; more decompositions exist.
