I lost a significant ammout of solona by mistake to offcurve account

I accidentally sent 3.178179538 SOL to the address HK24enuksj4kpH5wzdTTVfonpYjFjKcaSofZbzNtLH9 instead of my intended address (I omitted the last character). Solscan shows:

  • Owner: System Program
  • isOnCurve: false
  • Balance: 3.178179538 SOL
  • Transaction signature: 3CJR9VvwCpuRCUowBZAb4XCK6vdKxwLJJKJ94dax4zVuQ9cBDCdH9PurmEM6xpKSenqZKYcXY1TvwYVCMj3uEzkz

Is there any technical method to recover funds from this off-curve System Program account, or are they permanently inaccessible?
