Worth remembering that if you need that much force to remove the BB, it's more than likely that the person who fitted it (might be you, might be previous owner) did something wrong.
No grease, didn't clean threads, too tight etc.
Could also just be that you left it too long between maintenance but I find even very very old BB that installed properly come out easily.
In other words, don't make any of those mistakes when reinstalationing.
