Theorem nnsum4primesodd 46450

Description: If the (weak) ternary Goldbach conjecture is valid, then every odd integer greater than 5 is the sum of 3 primes. (Contributed by AV, 2-Jul-2020.)

**Assertion**
Ref	Expression
nnsum4primesodd	⊢ (∀𝑚 ∈ Odd (5 < 𝑚 → 𝑚 ∈ GoldbachOddW ) → ((𝑁 ∈ (ℤ_≥‘6) ∧ 𝑁 ∈ Odd ) → ∃𝑓 ∈ (ℙ ↑_m (1...3))𝑁 = Σ𝑘 ∈ (1...3)(𝑓‘𝑘)))

Distinct variable group: 𝑓,𝑁,𝑘,𝑚

Proof of Theorem nnsum4primesodd Dummy variables 𝑝 𝑞 𝑟 are mutually distinct and distinct from all other variables.
