Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476138, here are decompositions:

11 + 2147476127 = 2147476138
29 + 2147476109 = 2147476138
107 + 2147476031 = 2147476138
167 + 2147475971 = 2147476138
239 + 2147475899 = 2147476138
347 + 2147475791 = 2147476138
617 + 2147475521 = 2147476138
641 + 2147475497 = 2147476138

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.226.170.

Address: 127.255.226.170
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.226.170
