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 two prime numbers greater than 2 is an even number. The sum of 2 and any other prime number is an odd number.

The sum of the two prime numbers 3 and 73 is 76.

The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.

The sum of two prime numbers will be composite unless one of the prime numbers is 2.
