Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489204, here are decompositions:

  • 61 + 2147489143 = 2147489204
  • 127 + 2147489077 = 2147489204
  • 181 + 2147489023 = 2147489204
  • 337 + 2147488867 = 2147489204
  • 463 + 2147488741 = 2147489204
  • 631 + 2147488573 = 2147489204
  • 661 + 2147488543 = 2147489204
  • 787 + 2147488417 = 2147489204

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.180.

Address
128.0.21.180
Class
public
IPv4-mapped IPv6
::ffff:128.0.21.180
