Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473004, here are decompositions:

41 + 31472963 = 31473004
113 + 31472891 = 31473004
137 + 31472867 = 31473004
191 + 31472813 = 31473004
197 + 31472807 = 31473004
281 + 31472723 = 31473004
467 + 31472537 = 31473004
503 + 31472501 = 31473004

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.61.108.

Address: 1.224.61.108
Class: public
IPv4-mapped IPv6: ::ffff:1.224.61.108

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.
