| Mar 30, 2019 at 20:09 | comment | added | Enzo Creti | @Gerhard Paseman 7 is the 4th prime, 8263 is the 1036th prime. 7/7(sum of digits of 7)=1 and 4# has 1 digit. 8263/19(sum of digits of 8263) is truncated equal to 434...1036# has 434 digits where # is primorial function | |

| Mar 28, 2019 at 18:54 | comment | added | Gerhard Paseman | I find these frequent edits go against the purpose of this forum. If you want to record frequent observations on a daily basis (whether they are significant or not), start a blog. You have asked a main question and gotten a reasonable answer; now move on. The numerology associated with the problem does not belong here. Next week, if you find a third prime satisfying the relations, you can report that here.

| Mar 26, 2019 at 15:13 | comment | added | Alex M. | Possible duplicate of Why do primes dislike dividing the sum of all the preceding primes? | |
| Mar 26, 2019 at 12:01 | comment | added | Enzo Creti | @Peter $8+2+6+3=19$. $8263+19-1=91^2$ where 91 is 19 reversed | |
| Mar 26, 2019 at 9:22 | comment | added | Peter | The second solution ($8263$) has some amazing properties : The sum of its digits, the sum of the squares of its digits and the sum of the fifth powers of its digits are prime as well as $$8^8+2^2+6^6+3^3$$ | |

| Mar 26, 2019 at 7:40 | comment | added | Enzo Creti | @Alex M.@Mark Fischler the heuristic is the same for primes p(n) dividing the sum of primes up to p(n+1) and for primes p(n) dividing the sum of primes up to p(n). But it seems that in the first case primes are rarer. Why? | |
