Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515476, here are decompositions:

47 + 515429 = 515476
107 + 515369 = 515476
197 + 515279 = 515476
239 + 515237 = 515476
389 + 515087 = 515476
509 + 514967 = 515476
587 + 514889 = 515476
617 + 514859 = 515476

Showing the first eight; more decompositions exist.
