Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479752, here are decompositions:

13 + 31479739 = 31479752
103 + 31479649 = 31479752
163 + 31479589 = 31479752
193 + 31479559 = 31479752
211 + 31479541 = 31479752
313 + 31479439 = 31479752
331 + 31479421 = 31479752
463 + 31479289 = 31479752

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.87.200.

Address: 1.224.87.200
Class: public
IPv4-mapped IPv6: ::ffff:1.224.87.200

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.
