Find the largest number that cannot be written
as a sum of distinct primes of the form 6*n+1.
(In reply to
thoughts by Charlie)
1.Maybe the wording is misleading, but we are looking for a sum
of distinct primes i.e. at least two addends, EACH 6n+1
2. It is d2.
Rem: There is a conjecture that the quantity of twin primes is infinite, so both 6n-1 & 6n+1 forms exist in infinite sets.
