Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491648, here are decompositions:

  • 41 + 2147491607 = 2147491648
  • 89 + 2147491559 = 2147491648
  • 101 + 2147491547 = 2147491648
  • 131 + 2147491517 = 2147491648
  • 431 + 2147491217 = 2147491648
  • 509 + 2147491139 = 2147491648
  • 521 + 2147491127 = 2147491648
  • 557 + 2147491091 = 2147491648

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.31.64.

Address
128.0.31.64
Class
public
IPv4-mapped IPv6
::ffff:128.0.31.64
