Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475122, here are decompositions:

  • 19 + 2147475103 = 2147475122
  • 61 + 2147475061 = 2147475122
  • 193 + 2147474929 = 2147475122
  • 241 + 2147474881 = 2147475122
  • 271 + 2147474851 = 2147475122
  • 313 + 2147474809 = 2147475122
  • 571 + 2147474551 = 2147475122
  • 631 + 2147474491 = 2147475122

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.222.178.

Address
