Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469220, here are decompositions:

  • 41 + 2147469179 = 2147469220
  • 47 + 2147469173 = 2147469220
  • 89 + 2147469131 = 2147469220
  • 107 + 2147469113 = 2147469220
  • 131 + 2147469089 = 2147469220
  • 173 + 2147469047 = 2147469220
  • 179 + 2147469041 = 2147469220
  • 227 + 2147468993 = 2147469220

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.199.164.

Address
127.255.199.164
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.199.164

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 23:13:40 UTC (weekday:Monday).

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