Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21552, here are decompositions:

23 + 21529 = 21552
29 + 21523 = 21552
31 + 21521 = 21552
53 + 21499 = 21552
59 + 21493 = 21552
61 + 21491 = 21552
71 + 21481 = 21552
151 + 21401 = 21552

Showing the first eight; more decompositions exist.
