Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587930, here are decompositions:

37 + 33587893 = 33587930
67 + 33587863 = 33587930
73 + 33587857 = 33587930
97 + 33587833 = 33587930
127 + 33587803 = 33587930
139 + 33587791 = 33587930
193 + 33587737 = 33587930
199 + 33587731 = 33587930

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.130.218.

Address: 2.0.130.218
Class: public
IPv4-mapped IPv6: ::ffff:2.0.130.218

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.
