Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511928, here are decompositions:

19 + 511909 = 511928
31 + 511897 = 511928
37 + 511891 = 511928
61 + 511867 = 511928
97 + 511831 = 511928
127 + 511801 = 511928
337 + 511591 = 511928
349 + 511579 = 511928

Showing the first eight; more decompositions exist.
