Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487632, here are decompositions:

11 + 33487621 = 33487632
41 + 33487591 = 33487632
53 + 33487579 = 33487632
71 + 33487561 = 33487632
89 + 33487543 = 33487632
181 + 33487451 = 33487632
239 + 33487393 = 33487632
313 + 33487319 = 33487632

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.251.16.

Address: 1.254.251.16
Class: public
IPv4-mapped IPv6: ::ffff:1.254.251.16

Public, routable address (assignable to a host on the internet).
