O Happy Prime

[BigGlenntheHeavy]

I'm a little prime as happy as can be,
Ill fortune is the sum of my digits three,
If I'm reversed, I look the same,
Can you tell me, "What's my name?"

Hello, BigGlenntheHeavy!

A cute problem . . .

I'm a little prime as happy as can be,
Ill fortune is the sum of my digits three,
If I'm reversed, I look the same,
Can you tell me, "What's my name?"

Drag your cursor between the asterisks.

*We want a 3-digit palindromic prime the sum of whose digits is 13.

The only solution is 373. *
