Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487558, here are decompositions:

  • 17 + 2147487541 = 2147487558
  • 107 + 2147487451 = 2147487558
  • 109 + 2147487449 = 2147487558
  • 149 + 2147487409 = 2147487558
  • 157 + 2147487401 = 2147487558
  • 199 + 2147487359 = 2147487558
  • 257 + 2147487301 = 2147487558
  • 311 + 2147487247 = 2147487558

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.15.70.

Address
128.0.15.70
Class
public
IPv4-mapped IPv6
::ffff:128.0.15.70
