| # --description--
 | |
| 
 | |
| The primes 3, 7, 109, and 673, are quite remarkable. By taking any two primes and concatenating them in any order the result will always be prime. For example, taking 7 and 109, both 7109 and 1097 are prime. The sum of these four primes, 792, represents the lowest sum for a set of four primes with this property.
 | |
| 
 | |
| Find the lowest sum for a set of five primes for which any two primes concatenate to produce another prime.
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| `primePairSets()` should return a number.
 | |
| 
 | |
| ```js
 | |
| assert(typeof primePairSets() === 'number');
 | |
| ```
 | |
| 
 | |
| `primePairSets()` should return 26033.
 | |
| 
 | |
| ```js
 | |
| assert.strictEqual(primePairSets(), 26033);
 | |
| ```
