Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517520, here are decompositions:

7 + 517513 = 517520
13 + 517507 = 517520
19 + 517501 = 517520
61 + 517459 = 517520
103 + 517417 = 517520
109 + 517411 = 517520
127 + 517393 = 517520
139 + 517381 = 517520

Showing the first eight; more decompositions exist.
