Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606390, here are decompositions:

17 + 33606373 = 33606390
19 + 33606371 = 33606390
23 + 33606367 = 33606390
29 + 33606361 = 33606390
47 + 33606343 = 33606390
71 + 33606319 = 33606390
73 + 33606317 = 33606390
89 + 33606301 = 33606390

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.202.246.

Address: 2.0.202.246
Class: public
IPv4-mapped IPv6: ::ffff:2.0.202.246

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.
