Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489920, here are decompositions:

  • 3 + 2147489917 = 2147489920
  • 11 + 2147489909 = 2147489920
  • 47 + 2147489873 = 2147489920
  • 71 + 2147489849 = 2147489920
  • 101 + 2147489819 = 2147489920
  • 269 + 2147489651 = 2147489920
  • 281 + 2147489639 = 2147489920
  • 383 + 2147489537 = 2147489920

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.128.

Address
128.0.24.128
Class
public
IPv4-mapped IPv6
::ffff:128.0.24.128
