Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577366, here are decompositions:

3 + 31577363 = 31577366
13 + 31577353 = 31577366
43 + 31577323 = 31577366
97 + 31577269 = 31577366
103 + 31577263 = 31577366
127 + 31577239 = 31577366
157 + 31577209 = 31577366
193 + 31577173 = 31577366

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.213.22.

Address: 1.225.213.22
Class: public
IPv4-mapped IPv6: ::ffff:1.225.213.22

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.
