I think the reason why a mersenne number can not expressed as the sum of two squared numbers, is shown in this pdf (On Page 2. Proposition 1)
http://www.math.uga.edu/~pete/4400twosquares.pdf This is a proof, that NONE number n with the form: can be expressed as sum of two squares. But every mersenne number has this form. >
