Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16428, here are decompositions:

7 + 16421 = 16428
11 + 16417 = 16428
17 + 16411 = 16428
47 + 16381 = 16428
59 + 16369 = 16428
67 + 16361 = 16428
79 + 16349 = 16428
89 + 16339 = 16428

Showing the first eight; more decompositions exist.
