Of course that depends on how fast (often) you breathe, which you neglected to include in the question.
Pulling a number out of thin air ... let's say you average 15 breaths a minute.
Then 1,000,000 breaths = 66,666 minutes = 1,111 hours = 46.3 days (all are rounded)

If you take a breath every two seconds (an abnormally fast rate of breathing), that is 2 million seconds, which is about 23 days
A million times as long as it takes you to take one breath. Suggestion: Control the time it takes you to take 100 breaths, to get a better average. Then multiply that by 10,000.
It would take about 3.2 years.
it would take over 19 million years
one million seconds or 16666.66 minutes or 277.77 hours or 11.57 days.
There are 60 seconds in a minute and 60 minutes in an hour so in 1,000,000 seconds there are 1,000,000/6060 = 277.76 hours in one million seconds.
