Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486470, here are decompositions:

11 + 2147486459 = 2147486470
47 + 2147486423 = 2147486470
71 + 2147486399 = 2147486470
83 + 2147486387 = 2147486470
131 + 2147486339 = 2147486470
149 + 2147486321 = 2147486470
359 + 2147486111 = 2147486470
449 + 2147486021 = 2147486470

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.11.6.
