Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491208, here are decompositions:

7 + 2147491201 = 2147491208
97 + 2147491111 = 2147491208
127 + 2147491081 = 2147491208
139 + 2147491069 = 2147491208
211 + 2147490997 = 2147491208
241 + 2147490967 = 2147491208
337 + 2147490871 = 2147491208
397 + 2147490811 = 2147491208

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.29.136.

Address: 128.0.29.136
