Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557122, here are decompositions:

3 + 33557119 = 33557122
59 + 33557063 = 33557122
113 + 33557009 = 33557122
233 + 33556889 = 33557122
281 + 33556841 = 33557122
311 + 33556811 = 33557122
353 + 33556769 = 33557122
449 + 33556673 = 33557122

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.10.130.

Address: 2.0.10.130
Class: public
IPv4-mapped IPv6: ::ffff:2.0.10.130

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