Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562504, here are decompositions:

3 + 31562501 = 31562504
37 + 31562467 = 31562504
73 + 31562431 = 31562504
157 + 31562347 = 31562504
223 + 31562281 = 31562504
241 + 31562263 = 31562504
367 + 31562137 = 31562504
397 + 31562107 = 31562504

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.155.8.

Address: 1.225.155.8
Class: public
IPv4-mapped IPv6: ::ffff:1.225.155.8

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.
