Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515248, here are decompositions:

11 + 515237 = 515248
17 + 515231 = 515248
137 + 515111 = 515248
281 + 514967 = 515248
359 + 514889 = 515248
389 + 514859 = 515248
401 + 514847 = 515248
479 + 514769 = 515248

Showing the first eight; more decompositions exist.
