Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518928, here are decompositions:

17 + 518911 = 518928
61 + 518867 = 518928
97 + 518831 = 518928
127 + 518801 = 518928
149 + 518779 = 518928
167 + 518761 = 518928
181 + 518747 = 518928
191 + 518737 = 518928

Showing the first eight; more decompositions exist.
