Lovely! What's not to like in those numbers?
Primes are great, because they are unique. They don't get mixed up with other, simpler, numbers.
46? Oh, how 23 and two-ish.
27? You think you've got something special...then you realize 3, 3 and 3. And 9. How common.

Now there's a little number you could love!
It happens to be Mersienne Prime 127 (aka 2^127 - 1), and held the largest prime record from 1876 until 1951. It will probably always be the largest prime calculated by hand.
