Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479400, here are decompositions:

  • 19 + 2147479381 = 2147479400
  • 61 + 2147479339 = 2147479400
  • 127 + 2147479273 = 2147479400
  • 211 + 2147479189 = 2147479400
  • 229 + 2147479171 = 2147479400
  • 271 + 2147479129 = 2147479400
  • 337 + 2147479063 = 2147479400
  • 433 + 2147478967 = 2147479400

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.239.104.

Address
127.255.239.104
Class
