"23 It is the smallest number that is the concatenation of two primes  
2 and 3. 237 is the smallest number that can be separated into two  
primes in two different ways: 2-37, 23-7..."

This sequence looks like an any-number version of A173935, in which  
case you can prepend a(0) = 1, and decide if you want to exclude a(1)  
= 22 (if so, in the interest of clarity, your wording will have to  
change slightly).
