Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476836, here are decompositions:

7 + 31476829 = 31476836
37 + 31476799 = 31476836
103 + 31476733 = 31476836
109 + 31476727 = 31476836
229 + 31476607 = 31476836
337 + 31476499 = 31476836
379 + 31476457 = 31476836
463 + 31476373 = 31476836

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.76.100.

Address: 1.224.76.100
Class: public
IPv4-mapped IPv6: ::ffff:1.224.76.100

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.
