Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423504, here are decompositions:

  • 43 + 2147423461 = 2147423504
  • 73 + 2147423431 = 2147423504
  • 157 + 2147423347 = 2147423504
  • 211 + 2147423293 = 2147423504
  • 223 + 2147423281 = 2147423504
  • 307 + 2147423197 = 2147423504
  • 367 + 2147423137 = 2147423504
  • 571 + 2147422933 = 2147423504

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.21.16.

Address
127.255.21.16
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.21.16

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 10:31:44 UTC (weekday:Monday).

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