Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147401976, here are decompositions:

  • 3 + 2147401973 = 2147401976
  • 19 + 2147401957 = 2147401976
  • 43 + 2147401933 = 2147401976
  • 229 + 2147401747 = 2147401976
  • 409 + 2147401567 = 2147401976
  • 463 + 2147401513 = 2147401976
  • 607 + 2147401369 = 2147401976
  • 673 + 2147401303 = 2147401976

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.192.248.

Address
127.254.192.248
Class
