Ummm... If I am correctly interpreting the question to be asking for a Prime number less than 19, whose digits added together are greater than 7, then the answer is 17. There really aren't many options here (1, 2, 3, 5, 7, 11, 13, 17), only three of which even have multiple digits (11, 13, 17). So... 177. qed?
47 is the prime number greater than 43 and less than 52.
The only prime number greater than 25 but less than 30 is 29. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In this case, 29 is not divisible by any other numbers except for 1 and itself, making it a prime number.
23 or 41

Prime number which is greater than 30 and less than 35 is 31.
'17' is a prime number. The sum of the digits is 1 + 7 = 8 > 7.
43
The new prime number, 2 multiplied by itself 57,885,161times, less one, has 17,425,170 digits.
Any prime number that has 0 as one of its digits, such as 101, 103, 107 or 109.
47 is the prime number greater than 43 and less than 52.
The prime number that is greater than 20 but less than 29 is 23.
37
23
17
The four numbers are: 113, 131, 151 and 191. For the product of the digits to be prime, the number must contain 2 ones - which greatly simplifies the exercise.
It could be 97 which is a prime number.
