Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620392, here are decompositions:

  • 5 + 33620387 = 33620392
  • 11 + 33620381 = 33620392
  • 41 + 33620351 = 33620392
  • 89 + 33620303 = 33620392
  • 191 + 33620201 = 33620392
  • 233 + 33620159 = 33620392
  • 263 + 33620129 = 33620392
  • 353 + 33620039 = 33620392

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.1.168.
