This makes no sense. When you combine two distributions, the mean of
the combined distribution must be between the means of the separate
distributions:
MU = (MU1*N1 + MU2*N2) / (N1 + N2)
Therefore if the mean of the big distribution is 50, it _can't_ be
split into two distributions whose means are both 25.
