I was wondering what the appropriate kaffarah is for 17 years of missed fasts?

Unfortunately, I lost my faith during college and wasn’t practicing for 17 years. Consequently, I’ve missed 17 full Ramadans and now that I am practicing again I am wondering how I can make up for this substantial gap. Any advice or insight would be very much appreciated.

You need to:
1- Re-make the lost days (17×30= 510 days).
2- Feed 60 poor people/ day, each 750gms of flour or rice (510x60x0.75= 22950 kg's). Therefore 22950/60=382.5 kg's/ person
