Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468690, here are decompositions:

  • 127 + 2147468563 = 2147468690
  • 193 + 2147468497 = 2147468690
  • 349 + 2147468341 = 2147468690
  • 373 + 2147468317 = 2147468690
  • 421 + 2147468269 = 2147468690
  • 457 + 2147468233 = 2147468690
  • 571 + 2147468119 = 2147468690
  • 727 + 2147467963 = 2147468690

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.197.146.

Address
