Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595746, here are decompositions:

23 + 31595723 = 31595746
29 + 31595717 = 31595746
59 + 31595687 = 31595746
89 + 31595657 = 31595746
173 + 31595573 = 31595746
179 + 31595567 = 31595746
263 + 31595483 = 31595746
353 + 31595393 = 31595746

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.28.226.

Address: 1.226.28.226
Class: public
IPv4-mapped IPv6: ::ffff:1.226.28.226

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.
