A problem 20 years into the future

This one's a wicked real life problem I can help you solve, because finance is NOT a fluke.

Suppose you are exactly 30 years old. You believe that you will be able to save for the next 20 years, until you are 50.
For 10 years following that till age 60, you will have a spike in your expenses due to your parents' health, children's wedding, and other needs, and you won't be able to save.

If you want to guarantee yourself 40,000 per month, starting one month after your 60th birthday, how much should you save every month, for the next 20 years?
Assume that your investments are expected to yield 8% annually and you are likely to live till age 80.
