      in the name of god
      hello to all
      these two problems have planned by me,2 years ago;
      try to solve them;but there are too easy,just for amusement:
      1.suppose this a,b are from N,and a,b>1,prove that,if a+b=p,and p is prime number
      then,(a,b)=1.
      ...........................
      2.find number of pairs (a,b),so a,b>1,,(a,b)=1 and a+b=p,that p is prime number.

      ~~~~~~~~~~~~~~~~
      and then
      under the protection of god.
