Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483200, here are decompositions:

  • 29 + 2147483171 = 2147483200
  • 131 + 2147483069 = 2147483200
  • 167 + 2147483033 = 2147483200
  • 251 + 2147482949 = 2147483200
  • 257 + 2147482943 = 2147483200
  • 263 + 2147482937 = 2147483200
  • 383 + 2147482817 = 2147483200
  • 389 + 2147482811 = 2147483200

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.254.64.

Address
127.255.254.64
Class
