Odd primes presumably means different primes. (rather than all the primes except 2, i.e. odd numbered primes)
Thus I fail to see how the number 6 (an even number greater than 4) can be partitioned into 2 odd primes. Unless of course you are considering the number 1 as a prime.
Of course 6 can be partitioned into 3 and 3 but then where does the 'odd prime' clause come in?
So I would word the conjecture in one of two ways -
"Every even number greater than 6 can be written as the sum of 2 different primes"
"Every even number greater than 4 can be written as sum of 2 primes which are not necessarily different"
Forgive me my ignorance... and thanks for the great article
