You may make minor adjustments to your itinerary after the visa is granted.
You may not present a false itinerary in order to get a visa. If you are found out, the visa will be cancelled, and getting a new one any time in the future will be difficult.
Apparently you have lied to get the visa. phoog made a good suggestion in his comment: turn the lie into a fact and to follow the itinerary which you have submitted. Sweden is quite nice in August, beautiful coasts, beautiful islands.
