Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491706, here are decompositions:

7 + 2147491699 = 2147491706
97 + 2147491609 = 2147491706
103 + 2147491603 = 2147491706
109 + 2147491597 = 2147491706
163 + 2147491543 = 2147491706
229 + 2147491477 = 2147491706
337 + 2147491369 = 2147491706
433 + 2147491273 = 2147491706

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.31.122.

Address: 128.0.31.122
