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.
37 and 5
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.

Answer: (5 & 37), (11 & 31), (13 & 29), (19 & 23)
The sum of the two prime numbers 3 and 73 is 76.
42 has three prime factors: 2, 3 and 7
5
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.
