Considering SS and pension as bond allocations to keep more equities in 401k/IRA’s

I will have 2100 SS, 1700 pension and another 850 pension for $4650 month or 55800 annually. This would be like drawing 4% off of a 1,395,000 portfolio. Assuming I have 500k in equities in a 401k for a simulated 1,895,000 portfolio. 1,395,000 divided by 1,895,000. This would effectively be 73% bonds and 23% equities assuming my 401k had 0% bonds. Am I looking at this all wrong? Or does this make sense?
