Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484618, here are decompositions:

5 + 2147484613 = 2147484618
7 + 2147484611 = 2147484618
17 + 2147484601 = 2147484618
101 + 2147484517 = 2147484618
127 + 2147484491 = 2147484618
157 + 2147484461 = 2147484618
179 + 2147484439 = 2147484618
241 + 2147484377 = 2147484618

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.202.
