Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491234, here are decompositions:

11 + 2147491223 = 2147491234
17 + 2147491217 = 2147491234
41 + 2147491193 = 2147491234
107 + 2147491127 = 2147491234
167 + 2147491067 = 2147491234
173 + 2147491061 = 2147491234
191 + 2147491043 = 2147491234
197 + 2147491037 = 2147491234

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.29.162.

Address: 128.0.29.162
Class: public
IPv4-mapped IPv6: ::ffff:128.0.29.162
