5939 is considered to be a right prime number because even if we remove any digit from right, it will still remain as prime.
i.e
5939 is a prime number
593 is a prime number
59 is a prime number
5 is a prime number

Can you find out three digits highest right prime number?

797

It can't start with 9 or 8 as they are not primes, so starts with 7:
7-79-797
