Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16554, here are decompositions:

7 + 16547 = 16554
61 + 16493 = 16554
67 + 16487 = 16554
73 + 16481 = 16554
101 + 16453 = 16554
103 + 16451 = 16554
107 + 16447 = 16554
127 + 16427 = 16554

Showing the first eight; more decompositions exist.
