Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16574, here are decompositions:

7 + 16567 = 16574
13 + 16561 = 16574
97 + 16477 = 16574
127 + 16447 = 16574
157 + 16417 = 16574
163 + 16411 = 16574
193 + 16381 = 16574
211 + 16363 = 16574

Showing the first eight; more decompositions exist.
