I do approve of using approaches from different fields of mathematics, and that even if the proof is flawed that it shows some new insights. (Compare the topological proof of the infinitude of primes, for example.)

Engineering College Bichitra Kalita, has claimed to have solved the famous
'Goldbach conjecture', one of the unsolved problems in mathematics, using a
new technique called the graph theory."
Kalita may have found an application of graph theory but the formulation
sounds like the newspaper hasn't had their article reviewed by a
mathematician. Graph theory predates Goldbachs 1742 conjecture.
Euler's paper on the Seven Bridges of Königsberg is from 1736 and considered
the first work on graph theory.
"Kalita's research work "Graph and Goldbach Conjecture" has been accepted by
the department of mathematics of University of Chemical Technology and
Metallurgy in Sofia, Bulgaria in July this year."
The only Google hit on "Graph and Goldbach Conjecture" is the newspaper
article. I don't know Bulgarian.
"The work will be published in the International Journal of Pure and Applied
Mathematics, Kalita informed."
Submitted or accepted? Does the newspaper even know the difference? They could
have misquoted Kalita.
Kalita already claimed to prove Goldbach's conjecture in 2006. The index at
http://www.bpas.in/journals/maths/2006/vol2.pdf does say:
PROOF OF GOLDBACH CONJECTURE AND RELATED CONJECTURES OF PRIME. 451-459"
I haven't seen the paper. Google doesn't find any other mention of it, except
the title in a long list of Indian science papers.
