Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497728, here are decompositions:

11 + 2147497717 = 2147497728
29 + 2147497699 = 2147497728
31 + 2147497697 = 2147497728
37 + 2147497691 = 2147497728
67 + 2147497661 = 2147497728
157 + 2147497571 = 2147497728
239 + 2147497489 = 2147497728
269 + 2147497459 = 2147497728

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.55.0.
