Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517580, here are decompositions:

3 + 517577 = 517580
31 + 517549 = 517580
67 + 517513 = 517580
73 + 517507 = 517580
79 + 517501 = 517580
109 + 517471 = 517580
163 + 517417 = 517580
181 + 517399 = 517580

Showing the first eight; more decompositions exist.
