Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500072, here are decompositions:

61 + 33500011 = 33500072
103 + 33499969 = 33500072
163 + 33499909 = 33500072
271 + 33499801 = 33500072
283 + 33499789 = 33500072
313 + 33499759 = 33500072
409 + 33499663 = 33500072
439 + 33499633 = 33500072

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.43.168.

Address: 1.255.43.168
Class: public
IPv4-mapped IPv6: ::ffff:1.255.43.168

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.
