27408 is a member of OEIS A103763: a(n) = digit reversal of A103741(n) - a(n) is a non-palindromic composite located between twin primes whose reverse, which is less than it, is also located between twin primes. The sequences can be generated as follows:

INPUT

L=[]

for p in prime_range(100000):

  if next_prime(p)-p==2:

    number1=(next_prime(p)+p)/2

    number2=int(str(number1) [::-1])

    if number1 != number2 and number2 < number1:

      if is_prime(number2-1) and is_prime(number2+1):

        L.append(number1)

print(L)

print()

R=[]

for n in L:

  R.append(int(str(n) [::-1]))

print(R)
