"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

= 22 (if so, in the interest of clarity, your wording will have to
change slightly).
