Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479548, here are decompositions:

  • 17 + 2147479531 = 2147479548
  • 31 + 2147479517 = 2147479548
  • 41 + 2147479507 = 2147479548
  • 59 + 2147479489 = 2147479548
  • 101 + 2147479447 = 2147479548
  • 127 + 2147479421 = 2147479548
  • 167 + 2147479381 = 2147479548
  • 199 + 2147479349 = 2147479548

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.239.252.

Address
127.255.239.252
Class
