499 is the smallest prime that is the sum of a prime number of first odd primes: 499 = 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 + 31 + 37 + 41 + 43 + 47 + 53 + 59 + 61.
499499 ends with the digits 499499. In general, its odd powers end with 499 and its even powers end with 001.
Separate 499 into two (49, 9) and three (4, 9, 9) groups and get two primes after replacing each subset with each subset with its square root, namely 73 and 233. Replacing each digit of these latter two primes with their cubes results in two new primes: 34327 and 82727.
