Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467748, here are decompositions:

29 + 31467719 = 31467748
71 + 31467677 = 31467748
101 + 31467647 = 31467748
197 + 31467551 = 31467748
239 + 31467509 = 31467748
251 + 31467497 = 31467748
281 + 31467467 = 31467748
311 + 31467437 = 31467748

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.40.228.

Address: 1.224.40.228
Class: public
IPv4-mapped IPv6: ::ffff:1.224.40.228

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.
