Do you have an annuity or a pension? You say 'I don't plan on selling it'... you can't sell a pension, so I'm wondering if you actually have an annuity. Or do you have the ability to take a lump sum from the pension?
Are you being given different payout options? The way you describe is a joint with 100% survivor. Is this the only option you're being given?
At age 43 you and your wife will have an (average) life expectancy of 38 years. $50,000 discounted at a 5% rate over that time period is roughly $850,000.
