Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467764, here are decompositions:

37 + 31467727 = 31467764
43 + 31467721 = 31467764
73 + 31467691 = 31467764
193 + 31467571 = 31467764
283 + 31467481 = 31467764
331 + 31467433 = 31467764
397 + 31467367 = 31467764
463 + 31467301 = 31467764

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.40.244.

Address: 1.224.40.244
Class: public
IPv4-mapped IPv6: ::ffff:1.224.40.244

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.
