Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16454, here are decompositions:

3 + 16451 = 16454
7 + 16447 = 16454
37 + 16417 = 16454
43 + 16411 = 16454
73 + 16381 = 16454
181 + 16273 = 16454
223 + 16231 = 16454
271 + 16183 = 16454

Showing the first eight; more decompositions exist.
