Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482442, here are decompositions:

151 + 2147482291 = 2147482442
211 + 2147482231 = 2147482442
349 + 2147482093 = 2147482442
379 + 2147482063 = 2147482442
421 + 2147482021 = 2147482442
541 + 2147481901 = 2147482442
631 + 2147481811 = 2147482442
769 + 2147481673 = 2147482442

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.251.74.

Address: 127.255.251.74
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.251.74
