Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16446, here are decompositions:

13 + 16433 = 16446
19 + 16427 = 16446
29 + 16417 = 16446
83 + 16363 = 16446
97 + 16349 = 16446
107 + 16339 = 16446
113 + 16333 = 16446
127 + 16319 = 16446

Showing the first eight; more decompositions exist.
