Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491970, here are decompositions:

67 + 2147491903 = 2147491970
73 + 2147491897 = 2147491970
139 + 2147491831 = 2147491970
271 + 2147491699 = 2147491970
367 + 2147491603 = 2147491970
373 + 2147491597 = 2147491970
397 + 2147491573 = 2147491970
433 + 2147491537 = 2147491970

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.32.130.

Address: 128.0.32.130
