Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613600, here are decompositions:

  • 3 + 33613597 = 33613600
  • 23 + 33613577 = 33613600
  • 29 + 33613571 = 33613600
  • 101 + 33613499 = 33613600
  • 107 + 33613493 = 33613600
  • 131 + 33613469 = 33613600
  • 233 + 33613367 = 33613600
  • 353 + 33613247 = 33613600

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.231.32.

Address
2.0.231.32
Class

IPv4-mapped IPv6
::ffff:2.0.231.32

Public, routable address (assignable to a host on the internet).

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
