Let S={1,2,3,4,5,6,7,8}S = \{1, 2, 3, 4, 5, 6, 7, 8\}S={1,2,3,4,5,6,7,8}. Consider a subset A⊆SA \subseteq SA⊆S. We define two properties for AAA: Property P1P_1P1​: AAA contains at least one prime number. Property P2P_2P2​: The sum of the elements in AAA is an even number. How many non-empty subsets A⊆SA \subseteq SA⊆S satisfy both Property P1P_1P1​ and Property P2P_2P2​?
