Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16658, here are decompositions:

7 + 16651 = 16658
97 + 16561 = 16658
139 + 16519 = 16658
181 + 16477 = 16658
211 + 16447 = 16658
241 + 16417 = 16658
277 + 16381 = 16658
409 + 16249 = 16658

Showing the first eight; more decompositions exist.
