Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497770, here are decompositions:

13 + 2147497757 = 2147497770
37 + 2147497733 = 2147497770
53 + 2147497717 = 2147497770
71 + 2147497699 = 2147497770
73 + 2147497697 = 2147497770
79 + 2147497691 = 2147497770
107 + 2147497663 = 2147497770
109 + 2147497661 = 2147497770

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.55.42.

Address: 128.0.55.42
Class: public
IPv4-mapped IPv6: ::ffff:128.0.55.42
