Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147453040, here are decompositions:

  • 41 + 2147452999 = 2147453040
  • 67 + 2147452973 = 2147453040
  • 157 + 2147452883 = 2147453040
  • 163 + 2147452877 = 2147453040
  • 193 + 2147452847 = 2147453040
  • 233 + 2147452807 = 2147453040
  • 283 + 2147452757 = 2147453040
  • 389 + 2147452651 = 2147453040

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.136.112.

Address
