Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147384676, here are decompositions:

  • 7 + 2147384669 = 2147384676
  • 23 + 2147384653 = 2147384676
  • 43 + 2147384633 = 2147384676
  • 67 + 2147384609 = 2147384676
  • 83 + 2147384593 = 2147384676
  • 139 + 2147384537 = 2147384676
  • 149 + 2147384527 = 2147384676
  • 167 + 2147384509 = 2147384676

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.125.100.

Address
