Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470342, here are decompositions:

  • 29 + 2147470313 = 2147470342
  • 113 + 2147470229 = 2147470342
  • 131 + 2147470211 = 2147470342
  • 359 + 2147469983 = 2147470342
  • 461 + 2147469881 = 2147470342
  • 683 + 2147469659 = 2147470342
  • 821 + 2147469521 = 2147470342
  • 1013 + 2147469329 = 2147470342

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.204.6.

Address
127.255.204.6
Class
loopback
IPv4-mapped IPv6
::ffff:127.255.204.6
