Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515298, here are decompositions:

5 + 515293 = 515298
19 + 515279 = 515298
61 + 515237 = 515298
67 + 515231 = 515298
71 + 515227 = 515298
107 + 515191 = 515298
149 + 515149 = 515298
211 + 515087 = 515298

Showing the first eight; more decompositions exist.
