The decomposition conjecture for shoreless continua

Let XX be a continuum with no shore points, let pXp\in X, and let X=X1XNX=X_1\oplus\cdots\oplus X_N denote a decomposition into subcontinua. A point is non-coastal in a subcontinuum if it is not a coastal point there. The decomposition conjecture. There is a decomposition

X=X1XNX=X_1\oplus\cdots\oplus X_N

such that

pX1XNp\in X_1\cap\cdots\cap X_N

and pp is non-coastal when treated as a point of each XnX_n. The claim is intended to make the spot-welding construction of two copies of H{\mathbb H}^* generic, but the stronger conjecture is false.
