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.**
