Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500520, here are decompositions:

11 + 500509 = 500520
19 + 500501 = 500520
37 + 500483 = 500520
47 + 500473 = 500520
61 + 500459 = 500520
89 + 500431 = 500520
103 + 500417 = 500520
107 + 500413 = 500520

Showing the first eight; more decompositions exist.
