How do I repair a broken joist that's ensconced in concrete?

How do I repair a broken joist that's ensconced in concrete?

(OP)
Hi all:

My wife and I are relocating and we have "an issue" that's scaring off potential buyers.

Under the heaviest part of our small, 75-year-old house, is a cracked joist.  The previous owner went notch-happy and now the joist has a major crack running through it that terminates under a notch where 1" pipe runs.  West of the split, the joist runs though the bathroom's concrete pan, and with only about 2-3" below the concrete line.

Here's what I did to fix the matter.  There was some sag in the beams North and South of the one that's cracked, so I took two lally columns and put a piece of 4x6 pressure-treated wood and jacked up the three joists at both east and west of the crack.  So, in other words, I have four lallies with two 4x6's bridging across the same three joists less than four feet apart.  I did it really just to be anal, but it's scaring buyers away like crazy.

Here's the question ... since replacing or sistering this beam is impossible due to the concrete pan, is there a less dramatic way of lending support to this broken joist?

Thanks in advance for your advice.
