Twin primes are pairs of numbers $p$ and $p+2$ such that both are primes-for instance, 5 and 7, 11 and 13, 41 and 43. The Twin Prime Conjecture says that there are infinitely many twin primes. Let $TwinPrime(n)$ be a predicate that is true if $n$ and $n+2$ are twin primes. ... ) $∃m. ∀n. n ≤ m$ implies TwinPrime(n) $∀m. ∃n. n ≤ m$ and TwinPrime(n) $∃m. ∀n.$ TwinPrime(n) implies $n ≤ m$
