Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470122, here are decompositions:

  • 11 + 2147470111 = 2147470122
  • 41 + 2147470081 = 2147470122
  • 79 + 2147470043 = 2147470122
  • 103 + 2147470019 = 2147470122
  • 139 + 2147469983 = 2147470122
  • 173 + 2147469949 = 2147470122
  • 179 + 2147469943 = 2147470122
  • 241 + 2147469881 = 2147470122

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.203.42.

Address
127.255.203.42
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.203.42

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 23:28:42 UTC (weekday:Monday).

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