Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511994, here are decompositions:

3 + 511991 = 511994
31 + 511963 = 511994
61 + 511933 = 511994
97 + 511897 = 511994
103 + 511891 = 511994
127 + 511867 = 511994
151 + 511843 = 511994
163 + 511831 = 511994

Showing the first eight; more decompositions exist.
