Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574372, here are decompositions:

3 + 31574369 = 31574372
43 + 31574329 = 31574372
139 + 31574233 = 31574372
199 + 31574173 = 31574372
241 + 31574131 = 31574372
331 + 31574041 = 31574372
373 + 31573999 = 31574372
541 + 31573831 = 31574372

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.201.100.

Address: 1.225.201.100
Class: public
IPv4-mapped IPv6: ::ffff:1.225.201.100

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.
