Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487942, here are decompositions:

  • 11 + 2147487931 = 2147487942
  • 43 + 2147487899 = 2147487942
  • 71 + 2147487871 = 2147487942
  • 73 + 2147487869 = 2147487942
  • 109 + 2147487833 = 2147487942
  • 113 + 2147487829 = 2147487942
  • 139 + 2147487803 = 2147487942
  • 163 + 2147487779 = 2147487942

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.198.

Address
128.0.16.198
Class
public
IPv4-mapped IPv6
::ffff:128.0.16.198
