Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511898, here are decompositions:

7 + 511891 = 511898
31 + 511867 = 511898
67 + 511831 = 511898
97 + 511801 = 511898
229 + 511669 = 511898
271 + 511627 = 511898
307 + 511591 = 511898
349 + 511549 = 511898

Showing the first eight; more decompositions exist.
