Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515256, here are decompositions:

19 + 515237 = 515256
23 + 515233 = 515256
29 + 515227 = 515256
83 + 515173 = 515256
103 + 515153 = 515256
107 + 515149 = 515256
113 + 515143 = 515256
167 + 515089 = 515256

Showing the first eight; more decompositions exist.
