Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499730, here are decompositions:

  • 67 + 33499663 = 33499730
  • 97 + 33499633 = 33499730
  • 109 + 33499621 = 33499730
  • 139 + 33499591 = 33499730
  • 157 + 33499573 = 33499730
  • 211 + 33499519 = 33499730
  • 223 + 33499507 = 33499730
  • 283 + 33499447 = 33499730

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.42.82.
