Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483824, here are decompositions:

  • 11 + 2147483813 = 2147483824
  • 41 + 2147483783 = 2147483824
  • 47 + 2147483777 = 2147483824
  • 131 + 2147483693 = 2147483824
  • 281 + 2147483543 = 2147483824
  • 347 + 2147483477 = 2147483824
  • 401 + 2147483423 = 2147483824
  • 587 + 2147483237 = 2147483824

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.176.

Address
128.0.0.176
Class
public
IPv4-mapped IPv6
::ffff:128.0.0.176
