Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618142, here are decompositions:

3 + 33618139 = 33618142
23 + 33618119 = 33618142
113 + 33618029 = 33618142
179 + 33617963 = 33618142
431 + 33617711 = 33618142
521 + 33617621 = 33618142
599 + 33617543 = 33618142
653 + 33617489 = 33618142

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.248.222.

Address: 2.0.248.222
Class: public
IPv4-mapped IPv6: ::ffff:2.0.248.222

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.
