Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515366, here are decompositions:

43 + 515323 = 515366
73 + 515293 = 515366
139 + 515227 = 515366
193 + 515173 = 515366
223 + 515143 = 515366
277 + 515089 = 515366
433 + 514933 = 515366
463 + 514903 = 515366

Showing the first eight; more decompositions exist.
