Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610744, here are decompositions:

3 + 31610741 = 31610744
37 + 31610707 = 31610744
103 + 31610641 = 31610744
157 + 31610587 = 31610744
163 + 31610581 = 31610744
181 + 31610563 = 31610744
223 + 31610521 = 31610744
241 + 31610503 = 31610744

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.87.120.

Address: 1.226.87.120
Class: public
IPv4-mapped IPv6: ::ffff:1.226.87.120

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.
