Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490400, here are decompositions:

  • 137 + 2147490263 = 2147490400
  • 239 + 2147490161 = 2147490400
  • 311 + 2147490089 = 2147490400
  • 347 + 2147490053 = 2147490400
  • 389 + 2147490011 = 2147490400
  • 431 + 2147489969 = 2147490400
  • 443 + 2147489957 = 2147490400
  • 491 + 2147489909 = 2147490400

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.26.96.

Address
128.0.26.96
Class
public
IPv4-mapped IPv6
::ffff:128.0.26.96
