Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484340, here are decompositions:

3 + 2147484337 = 2147484340
101 + 2147484239 = 2147484340
107 + 2147484233 = 2147484340
137 + 2147484203 = 2147484340
173 + 2147484167 = 2147484340
179 + 2147484161 = 2147484340
257 + 2147484083 = 2147484340
347 + 2147483993 = 2147484340

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.2.180.

Address: 128.0.2.180
Class: public
IPv4-mapped IPv6: ::ffff:128.0.2.180
