    Diophantine equation problem.

    Please, I need help (urgently) solving this Diophantine equation (proving that it doesn't have integer solutions):
    x^5-y^2=4
    Thanks in advance...

    There are no solutions modulo 11,22,33,44,55,66,77 . (It seems these are the only moduli without solutions...)
