Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147428352, here are decompositions:

  • 19 + 2147428333 = 2147428352
  • 109 + 2147428243 = 2147428352
  • 283 + 2147428069 = 2147428352
  • 331 + 2147428021 = 2147428352
  • 379 + 2147427973 = 2147428352
  • 571 + 2147427781 = 2147428352
  • 673 + 2147427679 = 2147428352
  • 709 + 2147427643 = 2147428352

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.40.0.

Address
