Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557960, here are decompositions:

  • 19 + 33557941 = 33557960
  • 43 + 33557917 = 33557960
  • 61 + 33557899 = 33557960
  • 67 + 33557893 = 33557960
  • 151 + 33557809 = 33557960
  • 193 + 33557767 = 33557960
  • 211 + 33557749 = 33557960
  • 223 + 33557737 = 33557960

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.13.200.
