Introduction

Palindromic numbers are numbers which read the same from
left to right (forwards) as from the right to left (backwards)
Here are a few random examples : 12921, 1960691, 389909983

Palindromic Sums of Powers of Consecutive Primes

[ May 27, 2001 ]
Hans Havermann, inspired by the topics of this page, programmed his 400 MHz iMac
using Mathematica 4 and got an impressive output after seven days of computation.
Palindromic Sums of Powers of Consecutive Primes
Here is his largest record
510808567765808015
which is the sum of the squares of the following 95 consecutive primes
733267332 + 733267692 + 733267872 + ... + 733283172 + 733283292 + 733283412

The exclusive Palindromic Prime number 373 can be expressed as a sequence of
Five Consecutive Primes in two ways :

373 = 67 + 71 + 73 + 79 + 83
373 = 32 + 52 + 72 + 112 + 132

Five Consecutive Primes starting from 7 are ideal candidates for creating two more palindromic numbers :

7 x 11 x 13 x 17 x 19 = 323323
72 + 112 + 132 + 172 + 192 = 989

```
