Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147380670, here are decompositions:

  • 7 + 2147380663 = 2147380670
  • 31 + 2147380639 = 2147380670
  • 283 + 2147380387 = 2147380670
  • 313 + 2147380357 = 2147380670
  • 397 + 2147380273 = 2147380670
  • 541 + 2147380129 = 2147380670
  • 571 + 2147380099 = 2147380670
  • 619 + 2147380051 = 2147380670

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.109.190.

Address
127.254.109.190
Class
