Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517478, here are decompositions:

7 + 517471 = 517478
19 + 517459 = 517478
61 + 517417 = 517478
67 + 517411 = 517478
79 + 517399 = 517478
97 + 517381 = 517478
211 + 517267 = 517478
229 + 517249 = 517478

Showing the first eight; more decompositions exist.
