Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480136, here are decompositions:

7 + 31480129 = 31480136
19 + 31480117 = 31480136
307 + 31479829 = 31480136
367 + 31479769 = 31480136
379 + 31479757 = 31480136
397 + 31479739 = 31480136
439 + 31479697 = 31480136
487 + 31479649 = 31480136

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.89.72.

Address: 1.224.89.72
Class: public
IPv4-mapped IPv6: ::ffff:1.224.89.72

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.
