Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467340, here are decompositions:

11 + 31467329 = 31467340
29 + 31467311 = 31467340
89 + 31467251 = 31467340
137 + 31467203 = 31467340
173 + 31467167 = 31467340
251 + 31467089 = 31467340
257 + 31467083 = 31467340
269 + 31467071 = 31467340

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.39.76.

Address: 1.224.39.76
Class: public
IPv4-mapped IPv6: ::ffff:1.224.39.76

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.
