Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511998, here are decompositions:

7 + 511991 = 511998
37 + 511961 = 511998
59 + 511939 = 511998
89 + 511909 = 511998
101 + 511897 = 511998
107 + 511891 = 511998
131 + 511867 = 511998
139 + 511859 = 511998

Showing the first eight; more decompositions exist.
