Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474964, here are decompositions:

97 + 31474867 = 31474964
163 + 31474801 = 31474964
181 + 31474783 = 31474964
271 + 31474693 = 31474964
277 + 31474687 = 31474964
463 + 31474501 = 31474964
541 + 31474423 = 31474964
601 + 31474363 = 31474964

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.69.20.

Address: 1.224.69.20
Class: public
IPv4-mapped IPv6: ::ffff:1.224.69.20

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.
