Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517780, here are decompositions:

17 + 33517763 = 33517780
83 + 33517697 = 33517780
167 + 33517613 = 33517780
281 + 33517499 = 33517780
311 + 33517469 = 33517780
467 + 33517313 = 33517780
509 + 33517271 = 33517780
521 + 33517259 = 33517780

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.112.212.

Address: 1.255.112.212
Class: public
IPv4-mapped IPv6: ::ffff:1.255.112.212

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.
