Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540034, here are decompositions:

3 + 31540031 = 31540034
67 + 31539967 = 31540034
103 + 31539931 = 31540034
271 + 31539763 = 31540034
277 + 31539757 = 31540034
307 + 31539727 = 31540034
373 + 31539661 = 31540034
613 + 31539421 = 31540034

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.67.66.

Address: 1.225.67.66
Class: public
IPv4-mapped IPv6: ::ffff:1.225.67.66

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.
