Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518958, here are decompositions:

5 + 518953 = 518958
47 + 518911 = 518958
127 + 518831 = 518958
149 + 518809 = 518958
151 + 518807 = 518958
157 + 518801 = 518958
179 + 518779 = 518958
191 + 518767 = 518958

Showing the first eight; more decompositions exist.
