The Goldbach conjectureThe binary Goldbach conjecture states that every positive even number n > 2 is the sum of two primes. The Hardy-Littlewood circle method is based on the set of integers, which are the zeros of the orthonormal (Fourier series based) basis functions of the L(2) Hilbert space on the unit circle. All attempts applying the Hardy-Littlewood circle method to prove the binary Goldbach conjecture failed due to the insufficient (purely Weyl sum based) bounds for the minor arcs. An alternative two semi-circle method is proposed, which is built on non-harmonic Fourier series and related Riesz bases on the unit circle. They are built on the imaginary parts a(n)of the zeros of the considered Kummer function and the real, negative zeros of the Digamma function. Both sequences enjoy similar properties enabling N. Levinson's "gap and density theorems". The theory of non-harmonic Fourier series is enabled by appropriately defined „retarded / condensed“ sequences in the form b(n):=(3*a(n)+a(n+1))/4 fulfilling the Kadec condition. Those sequences are supposed to govern the "even-semi-circle" resp. the "odd-semi-circle". At the same time, both semi-circles can be mapped onto the negative real line until +1/2 (hosting all negative zeros of the Digamma function) and the positive critical line (not hosting any zero of the considered Kummer function).
