Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617064, here are decompositions:

41 + 31617023 = 31617064
53 + 31617011 = 31617064
113 + 31616951 = 31617064
131 + 31616933 = 31617064
173 + 31616891 = 31617064
317 + 31616747 = 31617064
461 + 31616603 = 31617064
503 + 31616561 = 31617064

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.112.40.

Address: 1.226.112.40
Class: public
IPv4-mapped IPv6: ::ffff:1.226.112.40

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.
