I discovered a recent paper that offers a good literature overview on Goldbach's conjecture (2N=p+q, p,q=primes). It can downloaded at free from: http://vixra.org/pdf/1205.0108v1.pdf
Although it does not provide the complete mathematical proof, it shows many interesting numerical results such as an estimation of the pairs (p,q) that fufill the conjecture, which is shown to increase with N. I feel that this work may inspire some other researchers.
