Examples:
The patient had recurrent chest pain
The mathematics lecture was on recurrent relations
The first example might be said with "recurring" by someone who isn't a medical professional.
So ultimately, "recurring" is far more commonly used and in a wider set of circumstances. "Recurrent" is mostly used in technical fields.
Why do two such similar words exist in English? It's a result of how English vocabulary developed. "Recurrent" is more directly based on a Latin present participle whereas recurring is based on the English verb "recur" which derives from a Latin verb. This pattern occurs frequently in English as a result we end up with similar meaning terms which derive from the same source which are all used in English with varying frequencies and overlap.
