Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537704, here are decompositions:

13 + 31537691 = 31537704
17 + 31537687 = 31537704
73 + 31537631 = 31537704
101 + 31537603 = 31537704
113 + 31537591 = 31537704
131 + 31537573 = 31537704
157 + 31537547 = 31537704
197 + 31537507 = 31537704

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.58.40.

Address: 1.225.58.40
Class: public
IPv4-mapped IPv6: ::ffff:1.225.58.40

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.

Routing number

Federal Reserve

Federal Reserve district 3 (Philadelphia)

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
