Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584188, here are decompositions:

7 + 2147584181 = 2147584188
31 + 2147584157 = 2147584188
131 + 2147584057 = 2147584188
199 + 2147583989 = 2147584188
227 + 2147583961 = 2147584188
241 + 2147583947 = 2147584188
251 + 2147583937 = 2147584188
359 + 2147583829 = 2147584188

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.136.188.
