Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16620, here are decompositions:

13 + 16607 = 16620
17 + 16603 = 16620
47 + 16573 = 16620
53 + 16567 = 16620
59 + 16561 = 16620
67 + 16553 = 16620
73 + 16547 = 16620
101 + 16519 = 16620

Showing the first eight; more decompositions exist.
