Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554688, here are decompositions:

  • 47 + 33554641 = 33554688
  • 107 + 33554581 = 33554688
  • 109 + 33554579 = 33554688
  • 179 + 33554509 = 33554688
  • 317 + 33554371 = 33554688
  • 347 + 33554341 = 33554688
  • 397 + 33554291 = 33554688
  • 421 + 33554267 = 33554688

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.1.0.
