Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466666, here are decompositions:

  • 127 + 2147466539 = 2147466666
  • 179 + 2147466487 = 2147466666
  • 227 + 2147466439 = 2147466666
  • 239 + 2147466427 = 2147466666
  • 283 + 2147466383 = 2147466666
  • 307 + 2147466359 = 2147466666
  • 337 + 2147466329 = 2147466666
  • 347 + 2147466319 = 2147466666

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.189.170.

Address
127.255.189.170
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.189.170

Loopback (127.0.0.0/8) — refers to the local host. Not routable.

Unix timestamp

Interpreted as seconds since the Unix epoch (Jan 1 1970 UTC), this is 2038-01-18 22:31:06 UTC (weekday:Monday).

Many software systems represent time this way; very common in logs and APIs.
