Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497758, here are decompositions:

41 + 2147497717 = 2147497758
59 + 2147497699 = 2147497758
61 + 2147497697 = 2147497758
67 + 2147497691 = 2147497758
97 + 2147497661 = 2147497758
199 + 2147497559 = 2147497758
251 + 2147497507 = 2147497758
269 + 2147497489 = 2147497758

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.55.30.

Address: 128.0.55.30
Class: public
IPv4-mapped IPv6: ::ffff:128.0.55.30
