Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485490, here are decompositions:

43 + 2147485447 = 2147485490
67 + 2147485423 = 2147485490
79 + 2147485411 = 2147485490
109 + 2147485381 = 2147485490
181 + 2147485309 = 2147485490
223 + 2147485267 = 2147485490
229 + 2147485261 = 2147485490
349 + 2147485141 = 2147485490

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.7.50.
