Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484730, here are decompositions:

89 + 2147484641 = 2147484730
113 + 2147484617 = 2147484730
239 + 2147484491 = 2147484730
269 + 2147484461 = 2147484730
353 + 2147484377 = 2147484730
491 + 2147484239 = 2147484730
509 + 2147484221 = 2147484730
563 + 2147484167 = 2147484730

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.4.58.
