Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511958, here are decompositions:

19 + 511939 = 511958
61 + 511897 = 511958
67 + 511891 = 511958
127 + 511831 = 511958
157 + 511801 = 511958
331 + 511627 = 511958
367 + 511591 = 511958
379 + 511579 = 511958

Showing the first eight; more decompositions exist.
