Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497428, here are decompositions:

17 + 2147497411 = 2147497428
67 + 2147497361 = 2147497428
79 + 2147497349 = 2147497428
107 + 2147497321 = 2147497428
191 + 2147497237 = 2147497428
227 + 2147497201 = 2147497428
347 + 2147497081 = 2147497428
389 + 2147497039 = 2147497428

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.53.212.
