Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500980, here are decompositions:

  • 43 + 2147500937 = 2147500980
  • 71 + 2147500909 = 2147500980
  • 73 + 2147500907 = 2147500980
  • 101 + 2147500879 = 2147500980
  • 109 + 2147500871 = 2147500980
  • 167 + 2147500813 = 2147500980
  • 199 + 2147500781 = 2147500980
  • 257 + 2147500723 = 2147500980

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.180.

Address
128.0.67.180
Class
public
IPv4-mapped IPv6
::ffff:128.0.67.180
