Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486446, here are decompositions:

23 + 2147486423 = 2147486446
47 + 2147486399 = 2147486446
59 + 2147486387 = 2147486446
107 + 2147486339 = 2147486446
197 + 2147486249 = 2147486446
317 + 2147486129 = 2147486446
557 + 2147485889 = 2147486446
569 + 2147485877 = 2147486446

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.10.238.

Address: 128.0.10.238
