Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33532972, here are decompositions:

3 + 33532969 = 33532972
29 + 33532943 = 33532972
41 + 33532931 = 33532972
101 + 33532871 = 33532972
401 + 33532571 = 33532972
491 + 33532481 = 33532972
503 + 33532469 = 33532972
521 + 33532451 = 33532972

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.172.44.

Address: 1.255.172.44
Class: public
IPv4-mapped IPv6: ::ffff:1.255.172.44

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.
