Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476946, here are decompositions:

29 + 31476917 = 31476946
353 + 31476593 = 31476946
359 + 31476587 = 31476946
509 + 31476437 = 31476946
563 + 31476383 = 31476946
593 + 31476353 = 31476946
797 + 31476149 = 31476946
827 + 31476119 = 31476946

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.76.210.

Address: 1.224.76.210
Class: public
IPv4-mapped IPv6: ::ffff:1.224.76.210

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.
