22

This number is a composite.

The divisors of the 22 can be added to 22 in various combinations to form a larger semiprime, e.g., 22+1+2=25=5*5, 22+11=33=3*11, 22+11+1=34=2*17, 22+11+1+2=35=5*7, 22+22+11=55=5*11 and 22+22+11+2+1=58=2*29. Is there another semiprime that can produce more than six ways? [Bergot]
