Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489380, here are decompositions:

  • 83 + 2147489297 = 2147489380
  • 89 + 2147489291 = 2147489380
  • 137 + 2147489243 = 2147489380
  • 173 + 2147489207 = 2147489380
  • 293 + 2147489087 = 2147489380
  • 383 + 2147488997 = 2147489380
  • 461 + 2147488919 = 2147489380
  • 467 + 2147488913 = 2147489380

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.100.

Address
128.0.22.100
Class
public
IPv4-mapped IPv6
::ffff:128.0.22.100
