Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489248, here are decompositions:

  • 5 + 2147489243 = 2147489248
  • 41 + 2147489207 = 2147489248
  • 251 + 2147488997 = 2147489248
  • 389 + 2147488859 = 2147489248
  • 521 + 2147488727 = 2147489248
  • 557 + 2147488691 = 2147489248
  • 941 + 2147488307 = 2147489248
  • 1097 + 2147488151 = 2147489248

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.224.

Address
128.0.21.224
Class
public
IPv4-mapped IPv6
::ffff:128.0.21.224
