Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483858, here are decompositions:

199 + 2147483659 = 2147483858
211 + 2147483647 = 2147483858
229 + 2147483629 = 2147483858
271 + 2147483587 = 2147483858
829 + 2147483029 = 2147483858
907 + 2147482951 = 2147483858
937 + 2147482921 = 2147483858
991 + 2147482867 = 2147483858

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.210.
