Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545972, here are decompositions:

13 + 33545959 = 33545972
43 + 33545929 = 33545972
349 + 33545623 = 33545972
373 + 33545599 = 33545972
571 + 33545401 = 33545972
601 + 33545371 = 33545972
643 + 33545329 = 33545972
661 + 33545311 = 33545972

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.222.244.

Address: 1.255.222.244
Class: public
IPv4-mapped IPv6: ::ffff:1.255.222.244

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.
