Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511086, here are decompositions:

29 + 511057 = 511086
47 + 511039 = 511086
53 + 511033 = 511086
67 + 511019 = 511086
73 + 511013 = 511086
97 + 510989 = 511086
167 + 510919 = 511086
179 + 510907 = 511086

Showing the first eight; more decompositions exist.
