Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531656, here are decompositions:

  • 3 + 33531653 = 33531656
  • 43 + 33531613 = 33531656
  • 79 + 33531577 = 33531656
  • 97 + 33531559 = 33531656
  • 157 + 33531499 = 33531656
  • 229 + 33531427 = 33531656
  • 307 + 33531349 = 33531656
  • 337 + 33531319 = 33531656

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.167.8.
