Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443068, here are decompositions:

  • 11 + 2147443057 = 2147443068
  • 19 + 2147443049 = 2147443068
  • 47 + 2147443021 = 2147443068
  • 79 + 2147442989 = 2147443068
  • 107 + 2147442961 = 2147443068
  • 137 + 2147442931 = 2147443068
  • 167 + 2147442901 = 2147443068
  • 241 + 2147442827 = 2147443068

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.97.124.

Address
