Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551120, here are decompositions:

  • 7 + 33551113 = 33551120
  • 13 + 33551107 = 33551120
  • 67 + 33551053 = 33551120
  • 79 + 33551041 = 33551120
  • 139 + 33550981 = 33551120
  • 181 + 33550939 = 33551120
  • 199 + 33550921 = 33551120
  • 271 + 33550849 = 33551120

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.243.16.
