Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491586, here are decompositions:

3 + 2147491583 = 2147491586
13 + 2147491573 = 2147491586
43 + 2147491543 = 2147491586
109 + 2147491477 = 2147491586
313 + 2147491273 = 2147491586
337 + 2147491249 = 2147491586
349 + 2147491237 = 2147491586
367 + 2147491219 = 2147491586

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.31.2.
