How about this:

X             : integer range 2..8192;
X_hole     : integer range 1025..4096;
; other "holes" . . .

. . .

if an_integer not in X or else an_integer in X_hole then
    raise contraint_error;
end if;

. . .

; odd integers
if (an_integer not in X) or else (an_integer mod 2 = 0) then
    raise constrain_error;
end if;
