Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483930, here are decompositions:

  • 37 + 2147483893 = 2147483930
  • 43 + 2147483887 = 2147483930
  • 61 + 2147483869 = 2147483930
  • 73 + 2147483857 = 2147483930
  • 271 + 2147483659 = 2147483930
  • 283 + 2147483647 = 2147483930
  • 367 + 2147483563 = 2147483930
  • 433 + 2147483497 = 2147483930

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.1.26.

Address
128.0.1.26
Class
public
IPv4-mapped IPv6
::ffff:128.0.1.26
