Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508980, here are decompositions:

7 + 33508973 = 33508980
61 + 33508919 = 33508980
79 + 33508901 = 33508980
83 + 33508897 = 33508980
149 + 33508831 = 33508980
151 + 33508829 = 33508980
163 + 33508817 = 33508980
173 + 33508807 = 33508980

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.78.116.

Address: 1.255.78.116
Class: public
IPv4-mapped IPv6: ::ffff:1.255.78.116

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.
