The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.
The sum of the first five prime numbers is 28. The sum of the cubes of the first three prime numbers is 160. The average of 28 and 160 is 94.

Two prime numbers can have only one sum, not three different sums!
which three prime numbers have a sum of 59
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.

The sum of the first three prime numbers that end with a 9 (19,29,59) is 107
The sum of the three greatest prime numbers that are less than 39 is 97.
The only way for three prime numbers to have a sum of 42 is if one of the prime numbers is 2, as 2 is the only even prime number. The other two prime numbers must add up to 40, which can only be achieved by 3 and 37. Therefore, the three prime numbers that have a sum of 42 are 2, 3, and 37.
I believe it would be 3, 11 and 29... all prime numbers that sum to 43.
2, 3, and 13 are all prime numbers and their sum is equal to 18.
