Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470356, here are decompositions:

  • 23 + 2147470333 = 2147470356
  • 29 + 2147470327 = 2147470356
  • 43 + 2147470313 = 2147470356
  • 107 + 2147470249 = 2147470356
  • 127 + 2147470229 = 2147470356
  • 173 + 2147470183 = 2147470356
  • 179 + 2147470177 = 2147470356
  • 233 + 2147470123 = 2147470356

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.204.20.

Address
127.255.204.20
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.204.20

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 23:32:36 UTC (weekday:Monday).

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