Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498180, here are decompositions:

103 + 2147498077 = 2147498180
241 + 2147497939 = 2147498180
409 + 2147497771 = 2147498180
463 + 2147497717 = 2147498180
673 + 2147497507 = 2147498180
691 + 2147497489 = 2147498180
733 + 2147497447 = 2147498180
769 + 2147497411 = 2147498180

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.56.196.
