Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512928, here are decompositions:

7 + 512921 = 512928
11 + 512917 = 512928
29 + 512899 = 512928
37 + 512891 = 512928
79 + 512849 = 512928
107 + 512821 = 512928
109 + 512819 = 512928
131 + 512797 = 512928

Showing the first eight; more decompositions exist.
