Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33504780, here are decompositions:

17 + 33504763 = 33504780
137 + 33504643 = 33504780
139 + 33504641 = 33504780
149 + 33504631 = 33504780
163 + 33504617 = 33504780
223 + 33504557 = 33504780
227 + 33504553 = 33504780
229 + 33504551 = 33504780

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.62.12.

Address: 1.255.62.12
Class: public
IPv4-mapped IPv6: ::ffff:1.255.62.12

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.
