Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515108, here are decompositions:

19 + 515089 = 515108
67 + 515041 = 515108
241 + 514867 = 515108
277 + 514831 = 515108
367 + 514741 = 515108
397 + 514711 = 515108
439 + 514669 = 515108
457 + 514651 = 515108

Showing the first eight; more decompositions exist.
