Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531672, here are decompositions:

11 + 33531661 = 33531672
19 + 33531653 = 33531672
59 + 33531613 = 33531672
61 + 33531611 = 33531672
113 + 33531559 = 33531672
131 + 33531541 = 33531672
173 + 33531499 = 33531672
193 + 33531479 = 33531672

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.167.24.

Address: 1.255.167.24
Class: public
IPv4-mapped IPv6: ::ffff:1.255.167.24

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