Probably need to provide some more information to get good suggestions. For example, unless you have some income you didn't mention (still working, social security, pension, other?), you need to make some drastic changes to your expenses to make your money stretch. You could modify your portfolio for higher risk but it wouldn't make the kind of differences you might need. Some numbers to see where this comment comes from:
a typical 67 woman has ~10% chance of living another 30 yrs
If we look at your assets / expenses in FIRECalc: A different kind of retirement calculator
over a 30 yr timeframe with no added income.....
~85% chance you will run out of money
would need to cut expenses to ~ 40k per year (down from 84k/yr) to have a 95% of outliving your money.
Hopefully you still have some income so the above isn't your situation. Let us know a bit more about yourself / goals with this money. Lots of good people to help here.
