*Prime twins* (or *twin primes*)
are odd prime numbers that come in pairs: {3, 5}, {11, 13}, {17, 19}, {29, 31}.
Primes in each twin pair differ by two. (The exceptional pair {2, 3} is not usually included in prime twins.)
One can prove that each prime twin pair except {3, 5}
has the form {6*x* − 1, 6*x* + 1} for a certain integer *x*.
Most mathematicians believe that *there are infinitely many prime twins.*
This is the so-called *twin prime conjecture*; nobody has proved it thus far.

**A Famous Prime Twin**

The prime number 824633702441, which is a prime twin, is perhaps the most expensive number in history.
This number helped discover the floating-point division bug in the Intel Pentium processor, which eventually has cost
Intel 475 million dollars!
Professor Thomas R. Nicely, the discoverer of the bug, recalls:
