Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605320, here are decompositions:

  • 11 + 33605309 = 33605320
  • 29 + 33605291 = 33605320
  • 53 + 33605267 = 33605320
  • 101 + 33605219 = 33605320
  • 113 + 33605207 = 33605320
  • 167 + 33605153 = 33605320
  • 233 + 33605087 = 33605320
  • 431 + 33604889 = 33605320

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.198.200.
