9000 = 2 × 2 × 2 × 3 × 3 × 5 × 5 × 5
9000 = 123 × 4 × 5 × (6 × 7 + 8) × 9
9000 = 9 × 8 × (7 × 6 + 5 × 4 + 3 × 21)
9000 = 0^6 + 1^8 + 2^9 + 3^7 + 4^0 + 5^5 + 6^2 + 7^4 + 8^1 + 9^3
9000 = 30^2 + 90^2 = 54^2 + 78^2
Sum of P(i) from 1 to 9000 is 397219321 which is also Prime
Number k such that k^16 + 1 is prime.
