Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585990, here are decompositions:

7 + 33585983 = 33585990
19 + 33585971 = 33585990
43 + 33585947 = 33585990
83 + 33585907 = 33585990
103 + 33585887 = 33585990
131 + 33585859 = 33585990
211 + 33585779 = 33585990
283 + 33585707 = 33585990

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.123.70.

Address: 2.0.123.70
Class: public
IPv4-mapped IPv6: ::ffff:2.0.123.70

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.
