Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147520074, here are decompositions:

211 + 2147519863 = 2147520074
241 + 2147519833 = 2147520074
283 + 2147519791 = 2147520074
397 + 2147519677 = 2147520074
433 + 2147519641 = 2147520074
457 + 2147519617 = 2147520074
523 + 2147519551 = 2147520074
541 + 2147519533 = 2147520074

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.142.74.

Address: 128.0.142.74
Class: public
IPv4-mapped IPv6: ::ffff:128.0.142.74

Public, routable address (assignable to a host on the internet).
