Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592804, here are decompositions:

7 + 31592797 = 31592804
31 + 31592773 = 31592804
43 + 31592761 = 31592804
127 + 31592677 = 31592804
163 + 31592641 = 31592804
337 + 31592467 = 31592804
367 + 31592437 = 31592804
457 + 31592347 = 31592804

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.17.100.

Address: 1.226.17.100
Class: public
IPv4-mapped IPv6: ::ffff:1.226.17.100

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.
