Narrative:

Upon calling for taxi instructions from ramp in slc, ground control cleared us 'to runway 35 via taxiway east, H6, cross runway 34R.' after crossing runway 34R at H6 we continued toward runway 35 via back taxi on runway 32 (a normal taxi route at slc). At that time we switched to tower 118.3 and tower said we were not cleared onto runway 32. We replied that we had been cleared to runway 35 with no 'hold short' instructions. Both the first officer and I heard the clearance as above. There must have been a communication breakdown between the ground controller and the tower. We asked if we had caused a conflict and the tower said no.
