Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500100, here are decompositions:

  • 7 + 2147500093 = 2147500100
  • 19 + 2147500081 = 2147500100
  • 37 + 2147500063 = 2147500100
  • 103 + 2147499997 = 2147500100
  • 139 + 2147499961 = 2147500100
  • 271 + 2147499829 = 2147500100
  • 373 + 2147499727 = 2147500100
  • 397 + 2147499703 = 2147500100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.64.68.

Address
128.0.64.68
Class
public
IPv4-mapped IPv6
::ffff:128.0.64.68
