Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477948, here are decompositions:

  • 67 + 2147477881 = 2147477948
  • 97 + 2147477851 = 2147477948
  • 139 + 2147477809 = 2147477948
  • 211 + 2147477737 = 2147477948
  • 349 + 2147477599 = 2147477948
  • 739 + 2147477209 = 2147477948
  • 757 + 2147477191 = 2147477948
  • 919 + 2147477029 = 2147477948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.233.188.

Address
127.255.233.188
Class
