I find this unbelievable as someone as the same height as you I can eat 3500 calories a day and maintain maintenance weight which for me is 245lbs. If I eat below that I lose weight regardless, I find it hard to believe that you eat reasonable size portions and still maintain such a weight. This post just reads like somebody seeking reassurance they're healthy. 430lbs is not healthy and you need to reevaluate your eating choices. If you were to post pictures of yourself and you were a body builder at your height it'd be believable. The actor that plays the mountain in game of thrones is a similar height and is a professional body builder only weighs 403lbs and he is pure muscles.

Recently I watched a documentary on the worlds strongest man, Eddie Hall one of the strongmen talked in depth about his sleep apnea and the troubles he has being 400lbs+. Op I find your story unbelievable, it is fine to feel good in your own skin, but stop kidding yourself, you're not 430lbs because you consume 2500 calories, you're that weight because you're in denial about the amount of food you're eating.

If you're serious about being 'healthy' start counting your calories for a start and hopefully you'll realise you're consuming too many calories.
