Werner Sand sent the
following conjecture:

**Let t be
the minor partner of a twin prime (presumed there are infinitely many), then the infinite**

Product[1/(1-1/t)] (t=3...infinite) =
π
= 3.14159...

According to computations,
the product increases monotonously from 3/2 to
π
and at the point of t = 23887065569, it is = 3.024374573...

**Q.
What can you comment about this conjecture?**
