Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470378, here are decompositions:

  • 17 + 2147470361 = 2147470378
  • 149 + 2147470229 = 2147470378
  • 167 + 2147470211 = 2147470378
  • 239 + 2147470139 = 2147470378
  • 311 + 2147470067 = 2147470378
  • 359 + 2147470019 = 2147470378
  • 461 + 2147469917 = 2147470378
  • 719 + 2147469659 = 2147470378

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.204.42.

Address
127.255.204.42
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.204.42

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 23:32:58 UTC (weekday:Monday).

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