Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515202, here are decompositions:

11 + 515191 = 515202
29 + 515173 = 515202
53 + 515149 = 515202
59 + 515143 = 515202
113 + 515089 = 515202
263 + 514939 = 515202
269 + 514933 = 515202
313 + 514889 = 515202

Showing the first eight; more decompositions exist.
