Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489448, here are decompositions:

  • 7 + 2147489441 = 2147489448
  • 11 + 2147489437 = 2147489448
  • 47 + 2147489401 = 2147489448
  • 101 + 2147489347 = 2147489448
  • 149 + 2147489299 = 2147489448
  • 151 + 2147489297 = 2147489448
  • 157 + 2147489291 = 2147489448
  • 241 + 2147489207 = 2147489448

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.168.

Address
128.0.22.168
Class
public
IPv4-mapped IPv6
::ffff:128.0.22.168
