Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513028, here are decompositions:

11 + 513017 = 513028
29 + 512999 = 513028
101 + 512927 = 513028
107 + 512921 = 513028
137 + 512891 = 513028
179 + 512849 = 513028
281 + 512747 = 513028
311 + 512717 = 513028

Showing the first eight; more decompositions exist.
