Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500516, here are decompositions:

  • 17 + 2147500499 = 2147500516
  • 23 + 2147500493 = 2147500516
  • 173 + 2147500343 = 2147500516
  • 257 + 2147500259 = 2147500516
  • 269 + 2147500247 = 2147500516
  • 389 + 2147500127 = 2147500516
  • 467 + 2147500049 = 2147500516
  • 509 + 2147500007 = 2147500516

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.65.228.

Address
128.0.65.228
Class
public
IPv4-mapped IPv6
::ffff:128.0.65.228
