Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621760, here are decompositions:

47 + 33621713 = 33621760
131 + 33621629 = 33621760
149 + 33621611 = 33621760
167 + 33621593 = 33621760
269 + 33621491 = 33621760
353 + 33621407 = 33621760
449 + 33621311 = 33621760
461 + 33621299 = 33621760

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.7.0.

Address: 2.1.7.0
Class: public
IPv4-mapped IPv6: ::ffff:2.1.7.0

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.
