Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535052, here are decompositions:

19 + 31535033 = 31535052
41 + 31535011 = 31535052
53 + 31534999 = 31535052
71 + 31534981 = 31535052
139 + 31534913 = 31535052
173 + 31534879 = 31535052
179 + 31534873 = 31535052
181 + 31534871 = 31535052

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.47.204.

Address: 1.225.47.204
Class: public
IPv4-mapped IPv6: ::ffff:1.225.47.204

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.
