Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500042, here are decompositions:

  • 53 + 2147499989 = 2147500042
  • 89 + 2147499953 = 2147500042
  • 179 + 2147499863 = 2147500042
  • 503 + 2147499539 = 2147500042
  • 509 + 2147499533 = 2147500042
  • 521 + 2147499521 = 2147500042
  • 563 + 2147499479 = 2147500042
  • 641 + 2147499401 = 2147500042

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.64.10.

Address
128.0.64.10
Class
public
IPv4-mapped IPv6
::ffff:128.0.64.10
