Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16898, here are decompositions:
- 19 + 16879 = 16898
- 67 + 16831 = 16898
- 139 + 16759 = 16898
- 151 + 16747 = 16898
- 157 + 16741 = 16898
- 199 + 16699 = 16898
- 241 + 16657 = 16898
- 331 + 16567 = 16898
Showing the first eight; more decompositions exist.
