Just Solved 701 Problems On Brilliant

Yeah, I've just solved 701 Problems on Brilliant . I did notice a special property of the number 701.

The special property of the number 701 is that it is a prime number and when reversed that is 107 is also a prime number. There are many such numbers like 701 which is a prime number and when reversed is also a prime number.

I wanted to share the special property with you and so to enjoy the moment, I've come up with the following problem:

Find the sum of all the prime numbers less than 1000 with the property that when its digits are reversed, it is also a prime number.
