2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
The prime numbers 3 an 7 are both odd and sum to 10.
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
2+3+5
They are: 2+3+5 = 10
Prime numbers less than 10 = 2, 3, 5, 7The sum of prime numbers less than 10:= 2 + 3 + 5 + 7= 17
2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
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.

2+3+5
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.
They are: 2+3+5 = 10
10 = 2 + 3 +5
2 + 3 + 5 = 10
The sum of the two prime numbers 3 and 73 is 76.
There are no prime numbers greater than 10 that add up to 29. Since all prime numbers greater than 2 are odd numbers, no two prime numbers greater than 2 can have an even number for their sum.
