Also seen as
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.
