Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497978, here are decompositions:

  • 67 + 33497911 = 33497978
  • 181 + 33497797 = 33497978
  • 307 + 33497671 = 33497978
  • 727 + 33497251 = 33497978
  • 739 + 33497239 = 33497978
  • 907 + 33497071 = 33497978
  • 1069 + 33496909 = 33497978
  • 1117 + 33496861 = 33497978

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.35.122.

Address
