Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485280, here are decompositions:

13 + 2147485267 = 2147485280
19 + 2147485261 = 2147485280
79 + 2147485201 = 2147485280
139 + 2147485141 = 2147485280
223 + 2147485057 = 2147485280
331 + 2147484949 = 2147485280
547 + 2147484733 = 2147485280
601 + 2147484679 = 2147485280

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.96.
