Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606400, here are decompositions:

  • 29 + 33606371 = 33606400
  • 83 + 33606317 = 33606400
  • 101 + 33606299 = 33606400
  • 167 + 33606233 = 33606400
  • 173 + 33606227 = 33606400
  • 197 + 33606203 = 33606400
  • 227 + 33606173 = 33606400
  • 251 + 33606149 = 33606400

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.203.0.
