Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556550, here are decompositions:

3 + 33556547 = 33556550
19 + 33556531 = 33556550
43 + 33556507 = 33556550
67 + 33556483 = 33556550
127 + 33556423 = 33556550
151 + 33556399 = 33556550
193 + 33556357 = 33556550
211 + 33556339 = 33556550

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.8.70.

Address: 2.0.8.70
Class: public
IPv4-mapped IPv6: ::ffff:2.0.8.70

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.
