Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493262, here are decompositions:

11 + 31493251 = 31493262
13 + 31493249 = 31493262
61 + 31493201 = 31493262
71 + 31493191 = 31493262
109 + 31493153 = 31493262
131 + 31493131 = 31493262
179 + 31493083 = 31493262
193 + 31493069 = 31493262

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.140.142.

Address: 1.224.140.142
Class: public
IPv4-mapped IPv6: ::ffff:1.224.140.142

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.
