Composite, 2223= 3*3*13*19
57 is a composite number with factors 3 and 19.
2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
3 and 19
3 x 3 = 9 (Not a prime ; Composite) 1 x 19 = 19 ( Prime) 3 x 7 = 21 (Note a prime: Composite) 5 x 5 = 25 (Not a prime ; Composite).

No, 19 is prime. A composite number needs to have 3 or more factors. 19 has only 2 factors, 1 and itself, which makes it prime.
513 is not prime. 513 = 3 * 3 * 3 * 19

No. it is composite. 57 is divisible by 3 and 19 :)

693 can be divided by 3 ==> composite number. This is an easy prime because if you make a sum of all the digits: 6 + 9 + 3 = 18, if you can devide this sum by 3 than you can also divide the original number by 3.
Oh, dude, let me drop some knowledge on you. The sum of two prime numbers can totally be composite. Like, imagine adding 3 and 5, which are both prime, you get 8, which is composite. So, yeah, it's totally possible. Cool, right?
