    Hi  Franklin  Maximilian    It is right    Certainly  these unsolved problems are too difficult to solve    I tell you another too difficult theorem as follows
    If  Mersenne Prime exist infinitely then Amicable Quadruple exist infinitely    [ Proof ]    Here is the factorization of Amicable Quadruple which I computed
    It has Mersenne Prime as prime factor  so  the theorem is proved    But  I know the following is too difficult problem
           Does Mersenne Prime exist infinitely ?
    I give you  much easier unsolved problems  of Amicable Pair

    Does Amicable Pair coprime to 210 exist ?
    For example  coprime to 2  or  coprime to 6=2*3  or coprime to 30=2*3*5  exist
    Here is the list of Amicable Pair coprime to 30
    Does Amicable 7-tuple exist ?    Here is A233538     It has Amicable Triple to 6-tuple
    I am sure these two problems are much easier and they must exist

Even the existence of infinitely many Sophie Germain primes is an unproved conjecture.

    Hi  Robert
    Thanks for telling me the information 
   I wish that someone will prove it, especially some smart Mathematician will prove in future the pair  {p, 2*p + 1}  which are both Sophie
   German Primes exist infinitely
    Because  if the proof exists then it is possible to prove  {3, -1} Amicable Pair exist infinitely many, though
    the following is unsolved problem
           Does Amicable Pair exist infinitely many ?

Look up "Dickson's conjecture". AFAIK there is no known proof of any case 
of Dickson's conjecture with k > 1: the closest is Yitang Zhang's proof 
that there is some d (with an explicit bound) such that p and p+d are both 
prime infinitely often.
