Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475842, here are decompositions:

13 + 2147475829 = 2147475842
103 + 2147475739 = 2147475842
151 + 2147475691 = 2147475842
241 + 2147475601 = 2147475842
283 + 2147475559 = 2147475842
613 + 2147475229 = 2147475842
661 + 2147475181 = 2147475842
739 + 2147475103 = 2147475842

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.225.130.

Address: 127.255.225.130
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.225.130
