Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16456, here are decompositions:

3 + 16453 = 16456
5 + 16451 = 16456
23 + 16433 = 16456
29 + 16427 = 16456
107 + 16349 = 16456
137 + 16319 = 16456
227 + 16229 = 16456
233 + 16223 = 16456

Showing the first eight; more decompositions exist.
