Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478826, here are decompositions:

5 + 2147478821 = 2147478826
107 + 2147478719 = 2147478826
167 + 2147478659 = 2147478826
173 + 2147478653 = 2147478826
179 + 2147478647 = 2147478826
257 + 2147478569 = 2147478826
263 + 2147478563 = 2147478826
677 + 2147478149 = 2147478826

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.237.42.

Address: 127.255.237.42
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.237.42
