Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491934, here are decompositions:

31 + 2147491903 = 2147491934
37 + 2147491897 = 2147491934
97 + 2147491837 = 2147491934
103 + 2147491831 = 2147491934
331 + 2147491603 = 2147491934
337 + 2147491597 = 2147491934
397 + 2147491537 = 2147491934
457 + 2147491477 = 2147491934

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.32.94.
