Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487946, here are decompositions:

43 + 33487903 = 33487946
127 + 33487819 = 33487946
229 + 33487717 = 33487946
307 + 33487639 = 33487946
367 + 33487579 = 33487946
409 + 33487537 = 33487946
433 + 33487513 = 33487946
439 + 33487507 = 33487946

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.252.74.

Address: 1.254.252.74
Class: public
IPv4-mapped IPv6: ::ffff:1.254.252.74

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.
