Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505660, here are decompositions:

3 + 505657 = 505660
17 + 505643 = 505660
41 + 505619 = 505660
47 + 505613 = 505660
53 + 505607 = 505660
59 + 505601 = 505660
101 + 505559 = 505660
137 + 505523 = 505660

Showing the first eight; more decompositions exist.
