Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500166, here are decompositions:

  • 43 + 2147500123 = 2147500166
  • 73 + 2147500093 = 2147500166
  • 103 + 2147500063 = 2147500166
  • 283 + 2147499883 = 2147500166
  • 337 + 2147499829 = 2147500166
  • 439 + 2147499727 = 2147500166
  • 463 + 2147499703 = 2147500166
  • 619 + 2147499547 = 2147500166

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.64.134.

Address
128.0.64.134
Class
public
IPv4-mapped IPv6
::ffff:128.0.64.134
