      Is 69 a prime number? If not any prime number close to 69 , I take it.

                    lol good try but 25 is not a prime number 😛

                    mine's 37. No idea why but it pops up as soon as I finished reading the question.

                      131

                      It's a nice palindrome, plus, copied from Wikipedia…

                      131 is a Sophie Germain prime, an irregular prime, the second 3-digit palindromic prime, and also a permutable prime with 113 and 311. It can be expressed as the sum of three consecutive primes, 131 = 41 + 43 + 47. 131 is an Eisenstein prime with no imaginary part and real part of the form 3n - 1. Because the next odd number, 133, is a semiprime, 131 is a Chen prime.
