Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604174, here are decompositions:

37 + 31604137 = 31604174
241 + 31603933 = 31604174
331 + 31603843 = 31604174
373 + 31603801 = 31604174
457 + 31603717 = 31604174
463 + 31603711 = 31604174
607 + 31603567 = 31604174
1033 + 31603141 = 31604174

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.61.206.

Address: 1.226.61.206
Class: public
IPv4-mapped IPv6: ::ffff:1.226.61.206

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.
