Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515324, here are decompositions:

13 + 515311 = 515324
31 + 515293 = 515324
97 + 515227 = 515324
151 + 515173 = 515324
181 + 515143 = 515324
283 + 515041 = 515324
421 + 514903 = 515324
457 + 514867 = 515324

Showing the first eight; more decompositions exist.
