The sum of my ones digit and tens digit is 10.

So it has to be one of these nine:

19
28
37
46
55
64
73
82
91

My tens digit is less than my ones digit

That narrows it down to these four:

19
28
37
46

and both my digits are prime.

That narrows it down to 37

I am a prime number.

Indeed, 37 is a prime number.

What number am I?

37.
