Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515252, here are decompositions:

19 + 515233 = 515252
61 + 515191 = 515252
79 + 515173 = 515252
103 + 515149 = 515252
109 + 515143 = 515252
163 + 515089 = 515252
211 + 515041 = 515252
313 + 514939 = 515252

Showing the first eight; more decompositions exist.
