19 and 67 are prime numbers.
43 is the only prime number in that list; 33 and 63 are both divisible by 3.
two prime numbers when added together will equal 63: 2 + 61
3*3*7=63
2 is a prime because it can only be multiplied by 1x6 but 63 isn't
19 and 67 are prime numbers.
33 and 55 are divisible by 11. 63 is 7 x 9, so 19 and 67 are the prime numbers.
