What are 2 prime numbers whose sum is 999?

Answer 1

The answer must have an even number and an odd number, because if you add two odd numbers, the sum would be even. Therefore, the first answer is the only prime even number: 2. 2 + 997 is 999, so the other answer would be 997. 997+2 (!?!) 997+2 (!?!) 2 and 997
