Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16988, here are decompositions:
- 7 + 16981 = 16988
- 61 + 16927 = 16988
- 67 + 16921 = 16988
- 109 + 16879 = 16988
- 157 + 16831 = 16988
- 229 + 16759 = 16988
- 241 + 16747 = 16988
- 331 + 16657 = 16988
Showing the first eight; more decompositions exist.
