Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617132, here are decompositions:

31 + 31617101 = 31617132
59 + 31617073 = 31617132
83 + 31617049 = 31617132
103 + 31617029 = 31617132
109 + 31617023 = 31617132
181 + 31616951 = 31617132
199 + 31616933 = 31617132
229 + 31616903 = 31617132

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.112.108.

Address: 1.226.112.108
Class: public
IPv4-mapped IPv6: ::ffff:1.226.112.108

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.
