Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515308, here are decompositions:

29 + 515279 = 515308
71 + 515237 = 515308
197 + 515111 = 515308
359 + 514949 = 515308
419 + 514889 = 515308
449 + 514859 = 515308
461 + 514847 = 515308
467 + 514841 = 515308

Showing the first eight; more decompositions exist.
