Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489124, here are decompositions:

61 + 31489063 = 31489124
97 + 31489027 = 31489124
193 + 31488931 = 31489124
577 + 31488547 = 31489124
631 + 31488493 = 31489124
643 + 31488481 = 31489124
661 + 31488463 = 31489124
691 + 31488433 = 31489124

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.124.100.

Address: 1.224.124.100
Class: public
IPv4-mapped IPv6: ::ffff:1.224.124.100

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.
