Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481780, here are decompositions:

11 + 33481769 = 33481780
23 + 33481757 = 33481780
29 + 33481751 = 33481780
41 + 33481739 = 33481780
281 + 33481499 = 33481780
383 + 33481397 = 33481780
419 + 33481361 = 33481780
491 + 33481289 = 33481780

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.228.52.

Address: 1.254.228.52
Class: public
IPv4-mapped IPv6: ::ffff:1.254.228.52

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.
