Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485764, here are decompositions:

5 + 2147485759 = 2147485764
173 + 2147485591 = 2147485764
191 + 2147485573 = 2147485764
197 + 2147485567 = 2147485764
241 + 2147485523 = 2147485764
313 + 2147485451 = 2147485764
317 + 2147485447 = 2147485764
331 + 2147485433 = 2147485764

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.68.
