Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484180, here are decompositions:

13 + 2147484167 = 2147484180
19 + 2147484161 = 2147484180
71 + 2147484109 = 2147484180
97 + 2147484083 = 2147484180
137 + 2147484043 = 2147484180
139 + 2147484041 = 2147484180
173 + 2147484007 = 2147484180
181 + 2147483999 = 2147484180

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.2.20.
