Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404918, here are decompositions:

17 + 2147404901 = 2147404918
59 + 2147404859 = 2147404918
89 + 2147404829 = 2147404918
317 + 2147404601 = 2147404918
479 + 2147404439 = 2147404918
569 + 2147404349 = 2147404918
587 + 2147404331 = 2147404918
599 + 2147404319 = 2147404918

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.204.118.

Address: 127.254.204.118
