3719 A Proud Prime Number!

3719 is not just an old odd number

But a very odd number

With many unique qualities

It is a proud prime number

And not a common composite number

As it has only two divisors, itself and two

It is the smallest prime having all

The end digits of a multi-digit prime

What’s more it is also a rare “Emirp”

Which is “prime” spelled backwards

Being also prime when in reverse

As 9173 is also prime

Its uniqueness doesn’t end there

Its first two digits 37 is also prime

As are its middle 71 and final two 19

The middle two and final two digits

Of its 'Emirp”;  17 and 73 are also prime

But sadly, not its first two 91

As that is divisible by 13 and therefore composite

Finally, of  twenty-four permutations

Of our unique prime, six are also prime

But I will bore you no longer with the list

This so-called poem has 23 lines which is also prime!
