Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147517666, here are decompositions:

17 + 2147517649 = 2147517666
23 + 2147517643 = 2147517666
79 + 2147517587 = 2147517666
83 + 2147517583 = 2147517666
103 + 2147517563 = 2147517666
127 + 2147517539 = 2147517666
139 + 2147517527 = 2147517666
157 + 2147517509 = 2147517666

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.132.226.

Address: 128.0.132.226
