### 1+1 Theorem

What is the 1+1 theorem?

I have heard that a Chinese mathematician, J.R. Chen (same surname as
me, but no relation), proved some (1+2) theorem and was close to
proving the (1+1) theorem. He died in March this year, aged 63, and
was known for his exceptional talent in mathematics, his atrociously
poor health (he spent the last 13 years of his life in hospital), and
his total social withdrawal (to the extent that he would throw his
own money onto the ground for no apparent reason - he was totally
enveloped in his world of numbers). It's got something to do with some
Goldbach person. I have no idea who Goldbach actually is, but the
Chinese have apparently some mania about him. Dr. Chen was given a
national funeral when he finally died, leaving a wife who was 20 years
younger and a son who was 50 years younger than him. The (1+2) theorem
was renamed Chen's theorem.

But what is the 1+1 theorem? And has there been any progress in its
proof?

Goldbach's conjecture is that every even number greater than 2 is the
sum of two primes, e.g. 4 = 2+2,   6 = 3+3,    8=3+5 etc, etc.
