Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470084, here are decompositions:

  • 3 + 2147470081 = 2147470084
  • 17 + 2147470067 = 2147470084
  • 41 + 2147470043 = 2147470084
  • 101 + 2147469983 = 2147470084
  • 167 + 2147469917 = 2147470084
  • 491 + 2147469593 = 2147470084
  • 563 + 2147469521 = 2147470084
  • 593 + 2147469491 = 2147470084

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.203.4.

Address
127.255.203.4
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.203.4

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 23:28:04 UTC (weekday:Monday).

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