Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500864, here are decompositions:

  • 83 + 2147500781 = 2147500864
  • 101 + 2147500763 = 2147500864
  • 167 + 2147500697 = 2147500864
  • 251 + 2147500613 = 2147500864
  • 503 + 2147500361 = 2147500864
  • 521 + 2147500343 = 2147500864
  • 563 + 2147500301 = 2147500864
  • 617 + 2147500247 = 2147500864

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.64.

Address
128.0.67.64
Class
public
IPv4-mapped IPv6
::ffff:128.0.67.64
