Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550556, here are decompositions:

  • 43 + 33550513 = 33550556
  • 163 + 33550393 = 33550556
  • 229 + 33550327 = 33550556
  • 367 + 33550189 = 33550556
  • 439 + 33550117 = 33550556
  • 829 + 33549727 = 33550556
  • 883 + 33549673 = 33550556
  • 1129 + 33549427 = 33550556

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.240.220.

Address
1.255.240.220
Class
public
IPv4-mapped IPv6
::ffff:1.255.240.220

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.

Routing number
033550556
Federal Reserve
Federal Reserve district 3 (Philadelphia)

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