Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423100, here are decompositions:

  • 13 + 2147423087 = 2147423100
  • 73 + 2147423027 = 2147423100
  • 79 + 2147423021 = 2147423100
  • 113 + 2147422987 = 2147423100
  • 167 + 2147422933 = 2147423100
  • 227 + 2147422873 = 2147423100
  • 239 + 2147422861 = 2147423100
  • 281 + 2147422819 = 2147423100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.19.124.

Address
