debugging - Change pointer into stack using GDB

Question

(gdb) x/x $sp+0x10 show

0xabcd 1234

Than mean sp+0x10 value is 0xabcd and it's a pointer to 1234

How can I change this pointer to 0xbbbb that point to 5678?

If I tried set $sp+0x10 = 0xbbbb that corrupt the program because that change the stack.

How can I change that $sp+0x10 will point to 5678? something like set [$sp+0x10] = 5678
