Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483740, here are decompositions:

47 + 2147483693 = 2147483740
191 + 2147483549 = 2147483740
197 + 2147483543 = 2147483740
251 + 2147483489 = 2147483740
263 + 2147483477 = 2147483740
317 + 2147483423 = 2147483740
491 + 2147483249 = 2147483740
503 + 2147483237 = 2147483740

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.92.
