Ignore that count. I don't know where I got 11,294 from, the correct
figure is 10,358.

Oh, I seem to have found a bug in the _partitions() function. I believe it
is missing some of the partitions.

>>> list(_partitions(25, 24))
[(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2)]
>>> list(_partitions(25, 25))
[]
